COMBINED SPINAL AND EPIDURAL ANAESTHESIA WITH CHLOROPROCAINE FOR HYSTERECTOMY

CLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, Issue 1 2008
Run-Qiao Fu
SUMMARY 1The aim of the present study was to determine the clinical efficacy and safety of chloroprocaine (CP) for gynaecological surgery. 2One hundred and twenty gynaecological patients scheduled for hysterectomy were divided randomly into four groups: Group A (n = 30), 2.5% CP 1.0 mL; Group B (n = 30), 2.5% CP 1.2 mL; Group C (n = 30), 2.5% CP 1.4 mL; and Group D (n = 30), 2.5% CP 1.6 mL. The dose of CP used in each group was mixed with 1 mL vehicle containing 5% glucose and 1.5% ephedrine. Spinal anaesthesia was achieved by lumbar puncture in the L2,3 interspace and injection of the mixture. Wherever necessary, CP (2.5%) was used for epidural anaesthesia. 3Although the times to onset and peak effect, as well as the grade of motor block of the lower limbs (Bromage scale), were similar among the four groups, the level of the highest sensory nerve block increased gradually, from T7 (± 1), T6 (± 1), T4 (± 1) to T3 (± 1) in Groups A, B, C and D, respectively. The rate of unsatisfactory spinal anaesthesia was 80 and 16.7% in Groups A and B, respectively, and consequently epidural anaesthesia was superimposed in those patients for surgery to start. Spinal anaesthesia was very satisfactory for surgery in Groups C and D. In contrast, the incidence of hypotension in Groups B, C and D was 6.7, 16.7 and 67.7%, respectively; however, respiratory depression only occurred in Group D in nine cases (30%). No other adverse events or neurologic deficits were found. 4The present results suggest that 30,35 mg CP in a total volume of 2.2,2.4 mL used for spinal anaesthesia in hysterectomy is safe and efficient. The combination of spinal and epidural anaesthesia with 2.5% CP can achieve 100% satisfactory anaesthesia for this type of surgery. [source]


Endoluminal repair of distal aortic arch aneurysms causing aorto-vocal syndrome

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 10 2008
J. P. Morales
Summary Purpose:, We have evaluated the efficacy of endovascular repair of distal aortic arch aneurysms (DAAA) causing recurrent laryngeal nerve palsy. Material and methods:, Eight patients (five male and three female) with median age of 72 years (range: 59,80) presented with left recurrent laryngeal nerve palsy associated with DAAA. All patients were considered unfit for open surgery. The median aneurysm size was 5.9 cm (range: 5,7.3). Thirteen stents were deployed: eight Gore, four Endofit and one Talent. Epidural anaesthesia was used in all patients. The left subclavian artery was covered in all and the left common carotid in three who had a preliminary right to left carotid,carotid bypass. Routine follow-up (FU) was with computed tomography (CT) at 3,6 months and yearly thereafter. Results:, Exclusion of the aneurysm sac was achieved in all patients. Thirty-day mortality was 0%, with no paraplegia or stroke. Early complications included: rupture of the external iliac artery (one) and common femoral artery thrombectomy (one). One patient died of unknown cause at 17 months. The mean FU in the remaining seven patients was 21 months (range: 6,51). Aneurysm size decreased in five, was unchanged in one and increased in one. Three patients had improvement in voice quality postoperatively. One patient had a recurrent type 1 endoleak which was restented twice. No late deaths have occurred. Conclusion:, Though technically the procedures involved were more complicated, endovascular repair of DAAA causing aorto-vocal syndrome is safe and offers a realistic alternative to open surgery. Hoarseness of the voice can improve postoperatively and is associated with reduction in aortic sac diameter. [source]


Epidural anaesthesia as a complication of attempted brachial plexus blockade using the posterior approach

ANAESTHESIA, Issue 6 2006
R. S. Gomez
Summary We report a case of accidental epidural anaesthesia as a complication of attempted brachial plexus blockade using a posterior approach in a 31-year-old man scheduled to undergo elective shoulder surgery. The block was inserted with the patient in the lateral position before induction of general anaesthesia. On emergence from anaesthesia, the patient could breathe but could not move his arms. He had no pain sensation from the fifth cervical dermatome to the third thoracic dermatome bilaterally; this resolved 8 h after surgery and he was discharged well 2 days later. Although proponents of the posterior approach to the brachial plexus claim that its use is associated with a lower incidence of significant complications, this case proves that the technique is not devoid of potentially serious complications.

Effects of induced hyperthermia on pharmacokinetics of ropivacaine in rats

FUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 4 2010
Romain Guilhaumou
Abstract Ropivacaine is a local anaesthetic used for epidural anaesthesia and postoperative pain relief. Hyperthermia is a very common sign of infection associated with variations in physiological parameters, which may influence drugs pharmacokinetics. The aim of this study was to determine the effects of induced hyperthermia on ropivacaine pharmacokinetics in rats. Two groups of six rats were given a single subcutaneous ropivacaine injection. Hyperthermia-induced animals were placed in a water bath to obtain a stable mean core temperature of 39.7 °C. After blood samples collection, ropivacaine serum concentrations and pharmacokinetic parameters were determined. Two other groups of six rats were sacrificed 30 min after ropivacaine injection to determine serum and tissues (brain and heart) concentrations. Our results (median ± inter quartile range) reveal a significant increase of the total apparent clearance (0.0151 ± 0.000800 L/min vs. 0.0134 ± 0.00134 L/min), apparent volume of distribution (Vd) (2.19 ± 0.27 L vs. 1.57 ± 0.73 L) and a significant decrease in exposure (488 ± 50.6 mg.min/L vs. 572 ± 110 mg.min/L) in induced-hyperthermia group. We observed a significant increase in brain ropivacaine concentration in hyperthermic rats (8.39 ± 8.42 ,g/g vs. 3.48 ± 3.26 ,g/g) and no significant difference between cardiac concentrations in the two groups (5.38 ± 4.83 ,g/g vs. 3.73 ± 2.44 ,g/g). Results suggest a higher tissular distribution of ropivacaine and an increase in blood,brain barrier permeability during hyperthermia. The hyperthermia-induced increase in Vd could be responsible for an increase in cerebral ropivacaine toxicity. These experimental data provide a basis for future clinical investigations in relation to local anaesthetic use in hyperthermic patients. [source]

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2010
M. ELHAKIM
Background: During combined general and regional anaesthesia, it is difficult to use autonomic signs to assess whether wakefulness is suppressed adequately. We compared the effects of a dexmedetomidine,bupivacaine mixture with plain bupivacaine for thoracic epidural anaesthesia on intraoperative awareness and analgesic benefits, when combined with superficial isoflurane anaesthesia (<0.05 maximum alveolar concentration) in patients undergoing thoracic surgery with one-lung ventilation (OLV). Methods: Fifty adult male patients were randomly assigned to receive either epidural dexmedetomidine 1 ,g/kg with bupivacaine 0.5% (group D) or bupivacaine 0.5% alone (group B) after induction of general anaesthesia. Gasometric, haemodynamic and bispectral index values were recorded. Post-operative verbal rating score for pain and observer's assessment of alertness/sedation scale were determined by a blinded observer. Results: Dexmedetomidine reduced the use of supplementary fentanyl during surgery. Patients in group B consumed more analgesics and had higher pain scores after operation than patients of group D. The level of sedation was similar between the two groups in the ICU. Two patients (8%) in group B reported possible intraoperative awareness. There was a limited decrease in PaO2 at OLV in group D compared with group B (P<0.05). Conclusion: In thoracic surgery with OLV, the use of epidural dexmedetomidine decreases the anaesthetic requirements significantly, prevents awareness during anaesthesia and improves intraoperative oxygenation and post-operative analgesia.

Testing whether the epidural works: too time consuming?

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2010
J. LARSSON
Background: When using epidural anaesthesia (EDA) for pain relief after major surgery, a failure rate of 10% is common. A crucial step in improving the care of patients with EDA is to define the position of the epidural catheter. The aim of this study was to investigate how much time it takes to determine whether the block is sufficient by assessing the extent of loss of cold sensation before induction of anaesthesia. Methods: One hundred patients listed for abdominal surgery were included in the study. After an epidural catheter had been inserted and an intrathecal or an intravenous position had been made unlikely by the use of a test dose, the patient was given a bolus dose of local anaesthetic plus an opioid in the epidural catheter. The epidural block was tested every 2 min, starting at 5 min and ending at 15 min. When at least four segments were blocked bilaterally, the testing was stopped, the time was noted and the patient was anaesthetised. Results: An epidural block was demonstrated after 5,6 min in 37 patients, after 7,8 min in 43 additional patients and after 9,10 min in 15 patients. In one patient, it took 12 min and in three patients, it took 15 min. In two patients, no epidural block could be demonstrated. Conclusion: Testing an epidural anaesthetic before the induction of anaesthesia takes only 5,10 extra minutes. Knowing whether the catheter is correctly placed means better quality of care, giving the anaesthetist better prerequisites for taking care of the patient post-operatively. [source]


Intrathecal sufentanil decreases the median effective dose (ED50) of intrathecal hyperbaric ropivacaine for caesarean delivery

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 3 2010
X. CHEN
Background: The addition of opioid to local anaesthetics has become a well-accepted practice of spinal anaesthesia for caesarean delivery. Successful caesarean delivery anaesthesia has been reported with the use of a low dose of intrathecal hyperbaric ropivacaine coadministered with sufentanil. This prospective, double-blinded study determined the median effective dose (ED50) of intrathecal hyperbaric ropivacaine with and without sufentanil for caesarean delivery, to quantify the sparing effect of sufentanil on the ED50 of intrathecal hyperbaric ropivacaine. Methods: Sixty-four parturients undergoing elective caesarean delivery with combined spinal,epidural anaesthesia were randomized into two groups: Group R (ropivacaine) and Group RS (ropivacaine plus sufentanil 5 ,g). The initial dose of ropivacaine was 13 mg in Group R and 10 mg in Group RS. The effective dose was defined as a T6 level attained within 10 min and no supplemental epidural anaesthetic required during surgery. Effective or ineffective responses determined, respectively, a 0.3 mg decrease or increase of the dose of ropivacaine for the next patient using an up,down sequential allocation. Results: The ED50 of intrathecal ropivacaine was 11.2 mg [confidence interval (CI) 95%: 11.0,11.6] in Group R vs. 8.1 mg (CI 95%: 7.8,8.3) in Group RS. Motor block was markedly more intense in Group R than in Group RS, and the incidence of shivering was lower in Group RS than in Group R. There were no differences in the onset time of sensory block or motor block, in the incidence of hypotension, nausea and vomiting. Conclusion: Intrathecal sufentanil 5 ,g produced a 28% reduction of ED50 of intrathecal hyperbaric ropivacaine for caesarean delivery. [source]


Management of post-operative bladder spasm

JOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 1-2 2005
D Chiang
Objective: Pain management following bladder surgery in children is often complicated by bladder spasm. The overall severity of spasm can be reduced with opioids, anticholinergic medication and sedatives, although breakthrough spasms often occur. At the Royal Children's Hospital, Melbourne, intravesical bupivacaine has been used to manage postoperative bladder spasm to good effect. The administration of intravesical bupivacaine is analysed in this prospective audit of locally applied intravesical anaesthetic and compared with other methods. Method: From February to August 2003, histories of 58 patients who had intravesical bupivacaine were studied and compared with six other methods of management of postoperative bladder spasm. Conclusion: Data showed that epidural anaesthesia was the most effective treatment of pain, with a pain score reduction of 6.6, compared with a reduction of 6.1 with intravesical bupivacaine, and 4.5 using intravenous morphine. However, intravesical bupivacaine was the most effective method for the relief of bladder spasm. [source]


Patterns in current anaesthesiological peri-operative practice for colonic resections: a survey in five northern-European countries

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 9 2006
P. Hannemann
Background:, For colorectal surgery, evidence suggests that optimal management includes: no pre-operative fasting, a thoracic epidural analgesia continued for 2 days post-operatively, and avoidance of fluid overload. In addition, no long-acting benzodiazepines on the day of surgery and use of short-acting anaesthetic medication may be beneficial. We examined whether these strategies have been adopted in five northern-European countries. Methods:, In 2003, a questionnaire concerning peri-operative anaesthetic routines in elective, open colonic cancer resection was sent to the chief anaesthesiologist in 258 digestive surgical centres in Scotland, the Netherlands, Denmark, Sweden and Norway. Results:, The response rate was 74% (n = 191). Although periods of pre-operative fasting up to 48 h were reported, most (> 85%) responders in all countries declared to adhere to guidelines for pre-operative fasting and oral clear liquids were permitted until 2,3 h before anaesthesia. Solid food was permitted up to 6,8 h prior to anaesthesia. In all countries more than 85% of the responders indicated that epidural anaesthesia was routinely used. Except for Denmark, long-acting benzodiazepines were still widely used. Short-acting anaesthetics were used in all countries except Scotland where isoflurane is the anaesthetic of choice. With the exception of Denmark, intravenous fluids were used unrestrictedly. Conclusion:, In northern Europe, most anaesthesiologists adhere to evidence-based optimal management strategies on pre-operative fasting, thoracic epidurals and short-acting anaesthetics. However, premedication with longer-acting agents is still common. Avoidance of fluid overload has not yet found its way into daily practice. This may leave patients undergoing elective colonic surgery at risk of oversedation and excessive fluid administration with potential adverse effects on surgical outcome. [source]


Ultrasound control for presumed difficult epidural puncture

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2001
T. Grau
Background: The efficacy of epidural anaesthesia depends on the accurate identification of the epidural space (ES). Abnormal anatomical conditions may make the procedure difficult or impossible. The aim of this study was to investigate whether pre-puncture ultrasound examination of the spinal anatomy might be beneficial in expected cases of difficult epidural anaesthesia. Methods: We used digital ultrasound equipment with a 5-MHz transducer to assess the anatomy of the ES and the posterior parts of the spinal column. We examined 72 parturients with abnormal anatomical conditions who were scheduled for epidural anaesthesia. The women were randomised into two equal groups. In all patients, the standard loss of resistance technique was used. In the ultrasound group, an ultrasound examination of the appropriate spinal region was conducted prior to epidural puncture. ES depth seen on the ultrasound images was compared to the ES depth measured by the needle. We compared the number of puncture attempts with the standard method (control group) to the number of attempts under ultrasound guidance. Results: Ultrasonography significantly improved operating conditions for epidural anaesthesia. The maximum VAS scores and patient acceptance were significantly better. Conclusions: With ultrasound measurement of the ES depth, the quality of epidural anaesthesia was enhanced. [source]


Thoracic epidural anaesthesia and analgesia: United Kingdom practice

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 9 2000
F. O'Higgins
Background: Thoracic epidural analgesia has become increasingly practised in recent years. Complications are rare but potentially serious and, consequently, careful evaluation is required before undertaking this technique. The practice surrounding this procedure varies widely amongst anaesthetists. Methods: A postal survey to examine the practice of thoracic epidural analgesia was sent to all Royal College of Anaesthetists tutors in the United Kingdom. Results: Responses were received from 240 tutors, representing a return rate of 83%. When obtaining consent for thoracic epidural cannulation, 42% of respondents mentioned risk of a dural tap complication and 11% mentioned neurological damage. Fifty percent of respondents performed epidural cannulation following induction of general anaesthesia. The practice of epidural insertion in patients with abnormal coagulation varied, although over 80% of respondents did not consider concurrent treatment with either aspirin or non-steroidal anti-inflammatory drugs a contraindication. Sterile precautions for epidural insertion also varied between anaesthetists. Postoperatively, 95% of respondents used an opioid-based bupivacaine solution for epidural infusions, and these were most commonly nursed on general surgical wards (63%). Seventy-eight percent of hospitals provided an acute pain team to review epidural analgesia. Conclusion: In the United Kingdom, there is little consensus in the practice of thoracic epidural analgesia relating to the issues of informed consent, epidural cannulation in patients with deranged clotting and the sterile precautions taken prior to performing epidural insertion. Most respondents use an opioid-based bupivacaine solution to provide postoperative epidural analgesia. Most hospitals in the UK now provide an acute pain service for thoracic epidural follow-up.

Effect of epidural saline washout on regression of sensory and motor block after epidural anaesthesia with 2% lidocaine and fentanyl in elderly patients

ANAESTHESIA, Issue 3 2009
E. Y. Park
Summary Seventy elderly males received lumbar epidural anaesthesia with 12 ml of 2% lidocaine containing fentanyl 50 ,g. At the end of transurethral surgery, the washout group (n = 33) received an epidural bolus of 30 ml saline while the control group (n = 34) did not. Mean (SD) times to 1-grade (17.2 (11.9) vs 32.7 (11.3) min) and 2-grade regression (23.8 (12.2) vs 56.0 (23.9) min) of motor block, 3-dermatomal sensory regression (31.4 (11.6) vs 42.2 (14.4) min for cold and 30.8 (15.6) vs 40.6 (14.2) min for pinprick), and regression to S1 (57.7 (16.1) vs 76.2 (20.2) min for cold and 56.8 (17.3) vs 69.2 (16.2) min for pinprick) were significantly shorter in the washout group than the control group. There were no differences in postoperative pain scores and side effects between the two groups. We concluded that epidural washout facilitates regression of both motor and sensory block following epidural anaesthesia without reducing the postoperative analgesic benefit. [source]

Clinical results with a new acoustic device to identify the epidural space

ANAESTHESIA, Issue 8 2002
T. J. M. Lechner
Summary Fifty patients scheduled for surgery under lumbar epidural anaesthesia were included in a study toevaluate the possibility of localising the epidural space solely by means of an acoustic signal. With an experimental set-up, the pressure generated during the epidural puncture procedure was translated into a corresponding acoustic signal. One anaesthetist held the epidural needle with both hands and detected the epidural space by means of this acoustic signal. At the same time, a second anaesthetist applied the loss of resistance technique and functioned as control. In all patients the epidural space was located with the acoustic signal. This was confirmed by conventional loss of resistance in 49 (98%) of the patients; in one patient (2%) it was not. We conclude that it is possible to locate the epidural space using an acoustic signal alone. [source]

Tetralogy of Fallot: maternal and neonatal outcomes

BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 3 2008
E Gelson
We performed a retrospective cohort study of 26 pregnancies in 16 women with repaired tetralogy of Fallot (rTOF) delivering at the Chelsea and Westminster Hospital and compared them with 104 controls. The rate of antenatal complications was significantly higher in the rTOF group (30 cf. 13%). Use of epidural anaesthesia was higher (67 cf. 25%) in the rTOF group compared with controls, and the length of the second stage was shorter in both spontaneous and assisted deliveries. However, the mode of delivery and neonatal outcomes were similar in both groups. Mean birthweight centile was lower in the tetralogy of Fallot group, 26 versus 58 in the control group (P = 0.000001, Wilcoxon rank sum test). All women whose babies were <10th centile weight for gestational age had moderate to severe pulmonary regurgitation. [source]

Joanne Ellison Clinical Research Fellow
Objective To assess the safety and efficacy of enoxaparin use for thromboprophylaxis or treatment of venous thromboembolism during pregnancy. Design Retrospective review of casenotes of women who received enoxaparin during pregnancy. Setting Obstetric Medicine Unit at Glasgow Royal Maternity Hospital. Sample Data were obtained on 57 pregnancies in 50 women over six years. Methods Information was obtained from case records in relation to outcome measures, the presence of underlying thrombophilia and indication for anticoagulation. Main outcome measures Incidences of venous thromboembolism, haemorrhage, thrombocytopenia, peak plasma anti-factor Xa levels and symptomatic osteoporosis. Results There were no thromboembolic events in the thromboprophylaxis group. There were no incidences of heparin-induced thrombocytopenia. Twenty-two women had spinal or epidural anaesthesia and no complications were encountered. There was one instance of antepartum haemorrhage following attempted amniotomy in a woman with previously unknown vasa praevia. Two women sustained postpartum haemorrhage, both secondary to vaginal lacerations, resulting in blood loss > 1000 mL. Blood loss following caesarean section was not excessive. No instances of vertebral or hip fracture were encountered. The median peak plasma anti-factor Xa level on a dose of 40 mg once daily was 0.235 U/mL; peak plasma anti-factor Xa levels were not affected by gestational age. Conclusions The use of enoxaparin in pregnancy is associated with a low incidence of complications and a dose of 40 mg once daily throughout pregnancy provides satisfactory anti-factor Xa levels and appears effective in preventing venous thromboembolism.

Effect of anaesthetic agents administered to the mothers on transcutaneous bilirubin levels in the neonates

ACTA PAEDIATRICA, Issue 7 2010
S Alkan
Abstract Aim:, To investigate the effect of anaesthetic agents on transcutaneous bilirubin levels during the first 24 h in neonates delivered by caesarean section. Methods:, A total of 168 neonates delivered by caesarean section, during which sevoflurane was used for general anaesthesia (group A), bupivacaine for spinal anaesthesia (group B), levobupivacaine for epidural anaesthesia (group C) and 155 neonates delivered vaginally were included in the study. Transcutaneous bilirubin levels (TBLs) of infants were measured during the first 24 h and compared with each other. Results:, The TBLs in neonates delivered vaginally were higher than those delivered by caesarean section, but the difference was not significant. TBLs were higher in groups A and C than in group B (p = 0.034, p = 0.011 respectively). TBLs were higher in group C than in group A, but the difference was not significant (p > 0.05). When the groups were compared with vaginal delivery group, TBLs in groups A and C were found higher (p = 0.03, p = 0.022 respectively). Conclusion:, The route of delivery had no effect on TBL. While bupivacaine was found to have no effect on neonatal bilirubin levels, levobupivacaine increased neonatal biluribin levels, but further studies are needed for definite results. [source]


COMBINED SPINAL AND EPIDURAL ANAESTHESIA WITH CHLOROPROCAINE FOR HYSTERECTOMY

CLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, Issue 1 2008
Run-Qiao Fu
SUMMARY 1The aim of the present study was to determine the clinical efficacy and safety of chloroprocaine (CP) for gynaecological surgery. 2One hundred and twenty gynaecological patients scheduled for hysterectomy were divided randomly into four groups: Group A (n = 30), 2.5% CP 1.0 mL; Group B (n = 30), 2.5% CP 1.2 mL; Group C (n = 30), 2.5% CP 1.4 mL; and Group D (n = 30), 2.5% CP 1.6 mL. The dose of CP used in each group was mixed with 1 mL vehicle containing 5% glucose and 1.5% ephedrine. Spinal anaesthesia was achieved by lumbar puncture in the L2,3 interspace and injection of the mixture. Wherever necessary, CP (2.5%) was used for epidural anaesthesia. 3Although the times to onset and peak effect, as well as the grade of motor block of the lower limbs (Bromage scale), were similar among the four groups, the level of the highest sensory nerve block increased gradually, from T7 (± 1), T6 (± 1), T4 (± 1) to T3 (± 1) in Groups A, B, C and D, respectively. The rate of unsatisfactory spinal anaesthesia was 80 and 16.7% in Groups A and B, respectively, and consequently epidural anaesthesia was superimposed in those patients for surgery to start. Spinal anaesthesia was very satisfactory for surgery in Groups C and D. In contrast, the incidence of hypotension in Groups B, C and D was 6.7, 16.7 and 67.7%, respectively; however, respiratory depression only occurred in Group D in nine cases (30%). No other adverse events or neurologic deficits were found. 4The present results suggest that 30,35 mg CP in a total volume of 2.2,2.4 mL used for spinal anaesthesia in hysterectomy is safe and efficient. The combination of spinal and epidural anaesthesia with 2.5% CP can achieve 100% satisfactory anaesthesia for this type of surgery. [source]


Convalescence after colonic surgery with fast-track vs conventional care

COLORECTAL DISEASE, Issue 8 2006
D. H. Jakobsen
Abstract Objective, To compare convalescence after colonic surgery with a fast-track rehabilitation programme vs conventional care. Background, Introduction of a multimodal rehabilitation programme (fast-track) with focus on epidural anaesthesia, minimal invasive surgical techniques, optimal pain control, and early nutrition and mobilization together with detailed patient information have led to a shorter hospital stay after colonic surgery. There are not much data on convalescence after discharge. Methods, A prospective, controlled, non-randomized interview-based assessment in 160 patients undergoing an elective, uncomplicated, open colonic resection or the Hartmann reversal procedure with a fast-track or a conventional care programme in two university hospitals. A structured interview-based assessment was performed preoperatively, and day 14 and 30 postoperatively. Results, Patients undergoing colonic surgery with a fast-track programme regained functional capabilities earlier with less fatigue and need for sleep compared with patients having conventional care. Despite early discharge of the fast-track patients (mean 3.4 days vs 7.5 days), no differences were found according to the need for home care, social care and visit to general practitioners, although the fast-track group had an increased number of visits at the outpatient clinic for wound care. More patients in the fast-track group were re-admitted, but the overall mean total hospital stay was 4.2 days vs 8.3 days in the conventional group. Conclusion, A fast-track rehabillitation programme led to a shorter hospital stay, less fatigue and earlier resumption of normal activities, without the increased need for support after discharge compared with conventionally treated patients after uncomplicated colonic resection.

The trouble with clinical indicators: Intact lower genital tract following childbirth in NSW Hospitals, 2003,2005

AUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 1 2010
Peter A. BAGHURST
Background:, The federal government wants outcomes of hospital care to be made publicly available. League tables based on single clinical indicators are misleading, largely because of their inability to take case-complexity into account. Aim:, To demonstrate the application of a graphical tool (the risk-adjusted funnel plot) to the comparison of clinical outcomes across hospitals; and its advantages over league tables. Methods:, We looked at publicly available data on intact lower genital tract (ILGT), for all hospitals in New South Wales at which more than 200 births occurred in 2005. The ,excess' percentage of women at each hospital with an ILGT following a vaginal birth, was calculated after adjustment for instrumental assistance, the use of epidural analgesia/anaesthesia, the use of induction/augmentation, and the number of births per annum. Results:, In 2005, ILGT ranged from 13.1 to 55.8%. A plot of ILGT against vaginal births per annum (a funnel plot) revealed huge heterogeneity among hospitals, and an inverse association with the number of births per annum. A residual funnel plot, constructed from the differences between observed and expected ILGT identified four hospitals (three public and one private) with consistently better ILGT than expected , and four public hospitals with ILGT consistently worse than expected. Some of these hospitals were not located at the extremes of the league table. Conclusion:, The risk-adjusted funnel plot is a useful graphical tool which may overcome the shortcomings of league tables. We need to become more sophisticated in our use of clinical indicators for comparing hospital performances. [source]
