ANAESTHESIA, Issue 9 2007
M. Hohlrieder
Summary In a randomised double blind prospective study, we tested the hypothesis that postoperative pain is lower in patients who receive an ProSeal LMAÔ laryngeal mask airway compared with a tracheal tube. One hundred consecutive female patients (ASA I,II, 18,75 years) undergoing laparoscopic gynaecological surgery were divided into two equal-sized groups for airway management with the ProSeal LMA or tracheal tube. Anaesthesia management was identical for both groups and included induction of anaesthesia using propofol/fentanyl, and maintenance with propofol/remifentanil, muscle relaxation with rocuronium, positive pressure ventilation, gastric tube insertion, dexamethasone/tropisetron for anti-emetic prophylaxis, and diclofenac for pain prophylaxis. All types of postoperative pain were treated using intravenous patient-controlled analgesia (PCA) morphine. Patients and postoperative staff were unaware of the airway device used. Data were collected by a single blinded observer. We found that pain scores were lower for the ProSeal LMA at 2 h and 6 h but not at 24 h. Morphine requirements were lower for the ProSeal LMA by 30.4%, 30.6% and 23.3% at 2, 6 and 24 h, respectively. Nausea was less common with the ProSeal LMA than with the tracheal tube at 2 h and 6 h but not at 24 h. There were no differences in the frequency of vomiting, sore throat, dysphonia or dysphagia. We conclude that postoperative pain is lower for the ProSeal LMA than the tracheal tube in females undergoing gynaecological laparoscopic surgery. [source]

Purpose: The aim of this study was to compare morphine consumption with patient-controlled analgesia (PCA) between spinal anesthesia (SA) (bupivacaine, morphine and fentanyl) and general anesthesia (GA) (sufentanil) after an abdominal hysterectomy. Methods: Forty women were randomly assigned to receive SA with bupivacaine 15 mg, 0.15 mg of intrathecal morphine and 15 ,g of fentanyl or GA with sufentanil, both combined with PCA. The primary outcome was morphine consumption with the PCA device. The secondary outcomes were post-operative pain at rest and under stress on a visual analog scale, nausea, pruritus and respiratory depression on a standardized scale. Outcome measures were recorded at 6, 12, 18, 24 and 48 h post-anesthesia. The duration of post-anesthesia care unit (PACU) and hospital stay were recorded. Results: Patients in the SA group consumed at least two times less morphine at each time interval than the GA group: at 48 h, they used 19 ± 17 vs. 81 ± 31 mg (P<0.0001). Post-operative pain at rest was lower in the SA group until the 18th hour and under stress until the 48th. There was more sedation in the GA group until the 18th hour. Little difference was observed in the incidence of pruritus. Nausea was more intense at the 6th hour in the GA group. There was no difference in the respiratory rate. The duration of PACU stay was shorter for the SA group (52 ± 9 vs. 73 ± 11 min, P<0.0001) as was the duration of hospital stay (2.2 ± 0.4 vs. 3.3 ± 0.7 days, P=0.01). Conclusions: It is concluded that intrathecal morphine 0.15 mg with 15 ,g of fentanyl decreases post-operative pain and morphine consumption by PCA without increasing adverse reactions for women undergoing an abdominal hysterectomy.

Laparoscopic resection with transcolonic specimen extraction for ileocaecal Crohn's disease,

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 4 2010

Background: Ileocolic resection for Crohn's disease can be performed entirely laparoscopically. However, an incision is needed for specimen extraction. This prospective observational study assessed the feasibility of endoscopic transcolonic specimen removal. Methods: Endoscopic specimen removal was attempted in a consecutive series of ten patients scheduled for laparoscopic ileocolic resection. Primary outcomes were feasibility, operating time, reoperation rate, pain scores, morphine requirement and hospital stay. To assess applicability, outcomes were compared with previous data from patients who had laparoscopically assisted operations. Results: Transcolonic removal was successful in eight of ten patients; it was considered not feasible in two patients because the inflammatory mass was too large (7,8 cm). Median operating time was 208 min and median postoperative hospital stay was 5 days. After surgery two patients developed an intra-abdominal abscess, drained laparoscopically or percutaneously, and one patient had another site-specific infection. The operation took longer than conventional laparoscopy, with no benefits perceived by patients in terms of cosmesis or body image. Conclusion: Transcolonic removal of the specimen in ileocolic Crohn's disease is feasible in the absence of a large inflammatory mass but infection may be a problem. It is unclear whether the technique offers benefit compared with conventional laparoscopic surgery. Copyright © 2010 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.

Intravenous magnesium sulfate for post-operative pain in patients undergoing lower limb orthopedic surgery

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 8 2009
A. DABBAGH
Introduction: This study looks at the effect of supplementary intravenous magnesium sulfate on acute pain when administered in patients undergoing lower limb orthopedic surgery using spinal anesthesia with bupivacaine. Method and materials: In this double-blind, randomized, placebo-controlled clinical trial, 60 patients were selected and randomly divided into two groups. Efforts were made to place both groups under the same method of anesthesia. One group received 8 mg/kg intravenous magnesium sulfate, started before the incision and continued up to the end of the surgical procedure, using a 50 ml syringe, via a peripheral large bore catheter; the second group received the same volume of placebos using the same method. To present the results, mean (± SD) was used; a P value of <0.05 was considered significant. Results: There was no difference between the two groups in terms of the basic variables. Pain reported by the first group that received magnesium sulfate was significantly less at the first, third, sixth and 12th hours after the operation in comparison with the group that received placebo. Also, the intravenous morphine requirements in the first 24 h after the surgery were less in the magnesium group (4.2 ± 1.6 mg) than in the control group (9.8 ± 2.1 mg). Conclusion: Intravenous magnesium sulfate can serve as a supplementary analgesic therapy to suppress the acute post-operative pain, leading to less morphine requirements in the first 24 h. [source]


Continuous incisional infusion of local anesthetic in pediatric patients following open heart surgery

PEDIATRIC ANESTHESIA, Issue 6 2009
CHRISTOPHER F. TIROTTA MD MBA
Summary Aim:, To determine the efficacy and safety of a continuous subcutaneous local anesthetic (LA) infusion in pediatric patients following open heart surgery. Background:, The use of a continuous LA infusion has been shown to be beneficial following adult cardiac surgery. To date there are no studies in the pediatric population. Methods/Materials:, Using a prospective, randomized, and double blind design, we compared LA, either 0.25% levobupivacaine or bupivacaine (Treatment Group) to saline (Placebo Group) delivered subcutaneously via a continuous infusion for 72 h after open heart surgery in 72 patients. Requirements for postoperative analgesics and pain scores were recorded for 72 h and plasma levels of local anesthetic were measured. Secondary outcomes measures included time to first oral intake, time to first bowel movement, time to urinary catheter removal, length of stay, requirements for antiemetics and additional sedation. Results:, Total morphine requirements over the first 24 h were less in the Treatment Group than the Placebo Group (0.05 mg·kg,1 vs 0.2 mg·kg,1, P = 0.007); this was true for all patient groups except those patients weighing less than 6.3 kg. The number of patients requiring no morphine was greater in the Treatment Group (7/35 vs 1/37, P = 0.02). The Treatment Group also received less midazolam, lorazepam, and ketorolac than the Placebo Group over 72 h due to the reduced clinical need for these agents in patients weighing less than 31 kg. There were no differences in secondary outcomes. Conclusions:, A continuous incisional infusion of LA reduced postoperative analgesic requirement and sedative use in pediatric patients undergoing a median sternotomy incision. Dosed at a maximum rate of 0.4 mg·kg,1·h,1, a continuous incisional infusion of LA is effective and safe for up to 72 h, with plasma levels of local anesthetic well below the toxic threshold. [source]
