Status Epilepticus,Induced Neuronal Loss in Humans Without Systemic Complications or Epilepsy

EPILEPSIA, Issue 8 2000
Denson G. Fujikawa
Summary: Purpose: To determine the regional distribution of neuronal damage caused strictly by status epilepticus (SE) without systemic complications, underlying brain pathology, or a history of preexisting epilepsy. Methods: The medical records and electroencephalograms (EEGs) of three deceased patients who developed SE in the hospital were reviewed. Their brains were formalin-fixed, and 17 brain regions were selected, embedded in paraffin, and sectioned. Alternate sections were stained with either hematoxylin and eosin and cresyl violet to determine the extent of neuronal loss and gliosis or glial fibrillary astrocytic protein to confirm the extent of astrocytic proliferation. Results: The three patients died 11 to 27 days after the onset of focal motor SE; none had hypotension, hypoxemia, hypoglycemia, or significant hyperthermia. Two patients had no prior seizures and no underlying brain pathology. The third patient, who had leptomeningeal carcinomatosis, had one seizure 2 months before the onset of SE. The duration of SE was 8.8 hours to 3 days. EEGs showed unilateral temporal lobe sharp-wave discharges in one patient and independent temporal lobe sharp-wave discharges bilaterally in the other two patients. In addition to widespread neuronal loss and reactive gliosis in the hippocampus, amygdala, dorsomedial thalamic nucleus, and Purkinje cell layer of the cerebellum, we report for the first time periamygdaloid (piriform) and entorhinal cortical damage occurring acutely after SE in humans. Conclusions: In the absence of systemic complications or preexisting epilepsy, SE produces neuronal loss in a distribution similar to that from domoic acid-induced SE in humans and from kainic acid- and pilocarpine-induced SE in rats.

Hypersensitivity reactions associated with endovascular devices

CONTACT DERMATITIS, Issue 1 2008
Golara Honari
Allergic reactions to endoprostheses are uncommon and reported in association with orthopaedic, dental, endovascular and other implanted devices. Hypersensitivity reactions to the biomaterials used in endovascular prostheses are among the infrequent reactions that may lead to local or systemic complications following cardiovascular therapeutic interventions. This article reviews potential immunotoxic effects of commonly used biomaterials. Reports of putative hypersensitivity reactions to endovascular devices, including coronary stents, perforated foramen occluders, pacemakers and implantable cardioverter defibrillators are also reviewed.

Complications of Minor Skin Surgery Performed under Local Anesthesia

DERMATOLOGIC SURGERY, Issue 8 2008
AVSHALOM SHALOM MD
BACKGROUND Minor surgical procedures performed under local anesthesia are the most common surgical procedures routinely carried out in every plastic surgical practice. OBJECTIVE The objective was to evaluate the prevalence of immediate local and systemic complications of such procedures. METHODS AND MATERIALS Records of 2,600 procedures performed under local anesthesia on 2,431 patients between November 2001 and May 2004 were reviewed. Local anesthetic complications and all surgical-related complications were recorded. RESULTS Procedure-related complications were 51 presyncope (1.9%), 4 true syncope (0.16%), 2 minor burns (0.08%), and 1 facial laceration (0.04%). CONCLUSIONS True allergic reaction to lidocaine is extremely rare and none was noted in our study. Most patients who claimed that they had suffered from such a reaction were probably experiencing symptoms related to intravenous injection administration, a reaction to the added vasoconstrictor (adrenaline), or a vasovagal reaction, which is a common trait among young adults.

Puffy hand syndrome due to drug addiction: a case,control study of the pathogenesis

ADDICTION, Issue 9 2006
Valérie Andresz
ABSTRACT Aim We studied the pathogenesis of puffy hand syndrome of intravenous drug use. We hypothesized that injections of high-dose sublingual buprenorphine, instead of the recommended sublingual administration, could play an important role in lymphatic obstruction and destruction. Design and participants We set up a case,control study in substitution centres, recruiting intravenous drug addicts with and without puffy hands, respectively. The subjects were asked to answer anonymously a questionnaire of 40 items comprising social and demographic status, history of illicit drugs use, buprenorphine misuse and injection practices. Findings We included 33 cases and 33 controls, mean age of 34 years. They were past heroin users, mainly methadone-substituted. In multivariate analysis, sex (women) (OR = 8.9, P = 0.03), injections in the hands (OR = 5.9, P = 0.03), injections in the feet (OR = 6.5, P = 0.01) and the absence of tourniquet (OR = 7.0, p = 0.02) were significant risk factors for puffy hand syndrome. In 69.7% of the cases and 59.4% of the controls, respectively, there was a high-dose sublingual buprenorphine misuse, although it appeared not to be a significant risk factor for puffy hand syndrome. Conclusions Injection practices are likely to cause puffy hands syndrome, but buprenorphine misuse should not be considered as a significant risk factor. However, intravenous drug users must still be warned of local and systemic complications of intravenous drug misuse. [source]

The role of calcimimetics in the treatment of hyperparathyroidism

EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 12 2007
R. P. Wüthrich
Abstract Calcimimetics reduce serum levels of parathyroid hormone (PTH) and calcium, with a leftward shift in the set-point for calcium-regulated PTH secretion. The aim of this publication is to review the data available for calcimimetics in primary, secondary and tertiary hyperparathyroidism (HPT). Parathyroidectomy (PTX) is currently the only curative treatment for primary HPT, and recommended for patients with moderate-to-severe disease, as defined by a 2002 National Institute's of Health summary statement. In general, patients with primary HPT not meeting these surgical criteria, as well as those with contraindication or refusal for surgery, are monitored for signs and symptoms of primary HPT. There are currently no non-surgical therapies approved for use in primary HPT, although bisphosphonates are used in some patients, in an effort to control serum calcium levels. Calcimimetics decrease PTH and calcium levels and are a potential alternative for patients contraindicated for PTX, or who have failed previous PTX and have recurrent primary HPT. Secondary HPT develops early in chronic kidney disease and is present virtually in all patients with end-stage renal disease (ESRD). Secondary HPT is a progressive disease and is associated with several systemic complications, including renal osteodystrophy, soft tissue and vascular calcifications, and adverse cardiovascular outcomes. In ESRD patients, calcimimetics were shown to simultaneously reduce PTH, calcium, phosphate and calcium × phosphate product. In addition, observational analyses of use of calcimimetics in the ESRD population have shown a reduction of important clinical outcomes. In renal allograft recipients with tertiary HPT and hypercalcaemia, calcimimetics are a promising treatment option to control the parameters of calcium phosphate metabolism and may be a valid alternative to PTX. Based on its unique mechanism of action, the calcimimetic cinacalcet may play a role in the medical treatment of primary and tertiary forms of HPT, in addition to the registered indication for the treatment of secondary HPT.

Complications of craniofacial resection for malignant tumors of the skull base: Report of an International Collaborative Study,

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 6 2005
Ian Ganly MD
Abstract Background. Advances in imaging, surgical technique, and perioperative care have made craniofacial resection (CFR) an effective and safe option for treating malignant tumors involving the skull base. The procedure does, however, have complications. Because of the relative rarity of these tumors, most existing data on postoperative complications come from individual reports of relatively small series of patients. This international collaborative report examines a large cohort of patients accumulated from multiple institutions with the aim of identifying patient-related and tumor-related predictors of postoperative morbidity and mortality and set a benchmark for future studies. Methods. One thousand one hundred ninety-three patients from 17 institutions were analyzed for postoperative mortality and complications. Postoperative complications were classified into systemic, wound, central nervous system (CNS), and orbit. Statistical analyses were carried out in relation to patient characteristics, extent of disease, prior radiation treatment, and type of reconstruction to determine factors that predicted mortality or complications. Results. Postoperative mortality occurred in 56 patients (4.7%). The presence of medical comorbidity was the only independent predictor of mortality. Postoperative complications occurred in 433 patients (36.3%). Wound complications occurred in 237 (19.8%), CNS-related complications in 193 (16.2%), orbital complications in 20 (1.7%), and systemic complications in 57 (4.8%) patients. Medical comorbidity, prior radiation therapy, and the extent of intracranial tumour involvement were independent predictors of postoperative complications. Conclusions. CFR is a safe surgical treatment for malignant tumors of the skull base, with an overall mortality of 4.7% and complication rate of 36.3%. The impact of medical comorbidity and intracranial tumor extent should be carefully considered when planning therapy for patients whose tumors are amenable to CFR. © 2005 Wiley Periodicals, Inc.

Free tissue transfer and local flap complications in anterior and anterolateral skull base surgery

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 10 2002
Jason A. Heth MD
Abstract Background Advances in reconstructive techniques over the past two decades have allowed the resection of more extensive skull base tumors than had previously been possible. Despite this progress, complications related to these cases remain a concern. Methods Univariate and multivariate analyses were used to determine the relationship of host, tumor, defect, treatment, and reconstructive variables to wound and systemic complications after anterior and anterolateral skull base resections. The study included 67 patients receiving local flap (LF) or free tissue transfer (FTT) reconstructions during an 8-year period. Results Overall, 28% of patients had a major wound complication, and 19% had a major systemic complication. LF and FTT flaps had similar rates of wound complications. LF reconstructions were associated with late wound breakdown problems, and FTT flap complications were primarily acute surgery,related problems. Conclusions The surgical reconstruction of skull base defects should be planned on the basis of the ability of the technique to attain safe closure and maintain integrity after radiation therapy. © 2002 Wiley Periodicals, Inc.

Central venous access for haemodialysis: prospective evaluation of possible complications

JOURNAL OF CLINICAL NURSING, Issue 2 2007
Denise De Andrade PhD
Aims and objectives., The combination of chronic renal insufficiency and haemodialysis represents a challenge for health professionals. Chronic renal insufficiency patients undergoing haemodialysis treatment through a temporary double-lumen catheter were prospectively studied in order to identify the type and frequency of local and systemic complications. Methods., A six-month period was established with a view to the inclusion of new cases. Data were acquired through interviews, clinical assessment and patient records, and entered into a Microsoft Excel database through a double entry system and exported to the Statistical Package Social Sciences software. Sixty-four patients were evaluated prospectively, of which thirty-eight (59.4%) were men and 35 (54.7%) required catheter insertion for immediate treatment. During the study period, 145 catheters were inserted, ranging from 1 to 7 implants per patient, 29 (45.3%) were single insertions and 127 (87.6%) catheters were inserted into the jugular vein. The catheters were left in place for an average of 30 days. Results., Forty-one (64%) presented inadequate functioning, after about 26 days. A febrile state occurred in 24 (37.5%) patients after 34 days, secretion at the catheter entry site in 27 (42.2% after 26 days and bloodstream infection was encountered in 34(53%) after 34 days. Of the 61 blood culture samples, thirty (49%) were positive for Staphylococcus aureus that was the microorganism most frequently isolated. Conclusion., The findings indicate worrying aspects such as the catheters permanence time, exposing patients to different complications, including infection. Furthermore, inadequate catheter functioning leads to inefficient haemodialysis treatment. Relevance to clinical practice., Knowledge about complications allows for systematic care planning, prevention and control actions. [source]


Four-year study of cobalt and chromium blood levels in patients managed with two different metal-on-metal total hip replacements

JOURNAL OF ORTHOPAEDIC RESEARCH, Issue 2 2003
Christian Lhotka
Abstract Background: Metal-on-metal total hip prostheses will produce a certain amount of wear debris. This results in increased whole-blood metal levels, which may cause adverse effects. It is not known to what extent the problem has been overcome by advances in alloy technology. Methods: In 259 patients who with total hip replacement, blood cobalt and chromium concentrations were measured with atomic absorption spectrophotometry over a period of four years after arthroplasty. Of the patients enrolled in the study, 131 had been managed with a METASUL® cobalt-chromium alloy metal-on-metal bearing combination, while 128 had been given a SIKOMET®-SM21® cobalt-chromium alloy metal-on-metal combination. The control group consisted of 31 age- and gender-matched subjects. Results: Compared with the controls, all the patients had higher cobalt and chromium levels. Cobalt concentrations were up to 50 times higher, while chromium concentrations were up to 100 times higher. Conclusions: Both systems showed evidence, in the whole-blood samples, of wear debris production by the implants. Therefore, patients managed with metal-on-metal bearing combinations should be carefully monitored in order to ensure that any local or systemic complications are detected early on. © 2002 Orthopaedic Research Society.

Severe hypokinesis caused by paraneoplastic anti-Ma2 encephalitis associated with bilateral intratubular germ-cell neoplasm of the testes

MOVEMENT DISORDERS, Issue 5 2007
Lumine Matsumoto MD
Abstract We report a 40-year-old man with severe hypokinesis as paraneoplastic manifestation of a microscopic "carcinoma in situ" of the testis. The young age of the patient, along with progressive neurologic deterioration, detection of anti-Ma2 antibodies, and ultrasound findings of bilateral microcalcifications, led to bilateral orchiectomy, revealing the tumor in both testes. After orchiectomy, neurological symptoms stabilized, but the patient eventually died of systemic complications caused by his severe neurological deficits. Anti-Ma2 paraneoplastic encephalitis should be considered in patients with severe hypokinesis, and intensive investigation and aggressive approach to treatment is encouraged to prevent progression of the neurological deficits. © 2006 Movement Disorder Society [source]


Prospective study of clinical symptoms and skin test reactions in medical students exposed to formaldehyde gas

THE JOURNAL OF DERMATOLOGY, Issue 5 2007
Sachiko TAKAHASHI
ABSTRACT Previous investigators have reported the occurrence of both allergic and non-allergic systemic complications due to exposure to formaldehyde gas. However, little is known about the pathogenic link between formaldehyde-induced clinical symptoms and patch test results, or about the long-term effects of formaldehyde exposure. In the present study, a questionnaire was administered to 143 medical students, and 60 of them were tested by patch test for formaldehyde at the beginning and end of a human anatomy laboratory course. Another group of 76 students who had finished the course 2,4 years previously were administered another questionnaire, and the patch test was carried out on 58 of them. The frequencies of skin irritation, eye soreness, lacrimation, eye fatigue, rhinorrhea, throat irritation, general fatigue and mood swings increased after repeated exposure. Two (3.3%) of 60 students became positive to 1% formaldehyde at the end of the anatomy course (one male with allergic hand dermatitis due to direct contact with formaldehyde, and one female with an atopic background with unbearable physical symptoms) while the remaining 58 showed a negative reaction throughout the study period. The vast majority of students complained of various non-allergic, physical symptoms, and recovered from such symptoms without subsequent complications. No progression to multiple chemical sensitivity was found. Students with an episode of atopic dermatitis and allergic rhinitis were susceptible to formaldehyde exposure, and developed mucocutaneous symptoms, probably due to the impaired barrier function and remodeling of the skin and mucosa.

Features and prognoses of infantile patients with atopic dermatitis hospitalized for severe complications

THE JOURNAL OF DERMATOLOGY, Issue 12 2006
Norito KATOH
ABSTRACT Although atopic dermatitis (AD) itself is regarded as a non-life threatening disease, childhood AD may be rarely accompanied by some serious complications. Six infantile AD patients who were hospitalized because of severe systemic complications, in addition to severe dermatitis on almost the entire body surface, are described. They were complicated by hypoproteinemia, hypovolemia, thrombocytosis, reduced serum immunoglobulin G, elevated serum liver enzymes and growth retardation. They had not been treated with topical corticosteroid before hospitalization. They were treated with topical corticosteroid and their eruption remarkably improved within 20 days (median) of hospitalization. Most of the abnormal clinical data including platelet numbers, serum levels of total protein, and liver enzymes had become normal at the day of discharge. After 30 ± 4 months of follow up, their skin condition was fair with daily application of moisturizer and occasional use of topical corticosteroid, without any systemic problems. Although severe infantile AD may be accompanied by potentially life-threatening systemic complications, their prognoses concerning AD are favorable if they are treated adequately from the beginning of their infancy.

The role of inflammatory and parenchymal cells in acute pancreatitis,

THE JOURNAL OF PATHOLOGY, Issue 3 2007
A Vonlaufen
Abstract The infiltration of inflammatory cells into the pancreas is an early and central event in acute pancreatitis that promotes local injury and systemic complications of the disease. Recent research has yielded the important finding that resident cells of the pancreas (particularly acinar and pancreatic stellate cells) play a dynamic role in leukocyte attraction via secretion of chemokines and cytokines and expression of adhesion molecules. Significant progress has been made in recent years in our understanding of the role of leukocyte movement (adhesion to the blood vessel wall, transmigration through the blood vessel wall and infiltration into the parenchyma) in the pathophysiology of acute pancreatitis. This review discusses recent studies and describes the current state of knowledge in the field. It is clear that detailed elucidation of the numerous processes in the inflammatory cascade is an essential step towards the development of improved therapeutic strategies in acute pancreatitis. Studies to date suggest that combination therapy targeting different steps of the inflammatory cascade may be the treatment of choice for this disease.

Regulation of membrane potential and fluid secretion by Ca2+ -activated K+ channels in mouse submandibular glands

THE JOURNAL OF PHYSIOLOGY, Issue 2 2007
Victor G. Romanenko
We have recently shown that the IK1 and maxi-K channels in parotid salivary gland acinar cells are encoded by the KCa3.1 and KCa1.1 genes, respectively, and in vivo stimulated parotid secretion is severely reduced in double-null mice. The current study tested whether submandibular acinar cell function also relies on these channels. We found that the K+ currents in submandibular acinar cells have the biophysical and pharmacological footprints of IK1 and maxi-K channels and their molecular identities were confirmed by the loss of these currents in KCa3.1- and KCa1.1 -null mice. Unexpectedly, the pilocarpine-stimulated in vivo fluid secretion from submandibular glands was essentially normal in double-null mice. This result and the possibility of side-effects of pilocarpine on the nervous system, led us to develop an ex vivo fluid secretion assay. Fluid secretion from the ex vivo assay was substantially (about 75%) reduced in animals with both K+ channel genes ablated , strongly suggesting systemic complications with the in vivo assay. Additional experiments focusing on the membrane potential in isolated submandibular acinar cells revealed mechanistic details underlying fluid secretion in K+ channel-deficient mice. The membrane potential of submandibular acinar cells from wild-type mice remained strongly hyperpolarized (,55 ± 2 mV) relative to the Cl, equilibrium potential (,24 mV) during muscarinic stimulation. Similar hyperpolarizations were observed in KCa3.1- and KCa1.1 -null mice (,51 ± 3 and ,48 ± 3 mV, respectively), consistent with the normal fluid secretion produced ex vivo. In contrast, acinar cells from double KCa3.1/KCa1.1 -null mice were only slightly hyperpolarized (,35 ± 2 mV) also consistent with the ex vivo (but not in vivo) results. Finally, we found that the modest hyperpolarization of cells from the double-null mice was maintained by the electrogenic Na+,K+ -ATPase. [source]

Is mechanical bowel preparation necessary in patients undergoing cystectomy and urinary diversion?

BJU INTERNATIONAL, Issue 9 2002
M. Shafii
Objective,To compare the surgical outcome in patients with or with no bowel preparation before cystectomy and ileal conduit urinary diversion, specifically assessing local and systemic complications. Patients and methods,All patients undergoing cystectomy and ileal conduit urinary diversion between January 1991 and December 1999 were assessed retrospectively. Twenty-two receive no bowel preparation (group 1) and were compared with 64 who had (group 2). Patients had similar demographic characteristics, stage and grade of tumour. Patients in group 2 received a standard 4-day bowel preparation and group 1 received no lavage or enemas. All patients underwent a standard iliac and obturator lymph node dissection, and cystoprostatectomy or anterior exenteration and ileal conduit urinary diversion. All patients received intraoperative metronidazole and gentamicin intravenously, and two further doses after surgery. Results,Deaths after surgery were comparable in the two groups (two in group 1 and four in group 2) and the incidence of wound infection was similar (three and seven, respectively). There were no significant differences between the respective groups for fistula and anastomotic dehiscence (two and six) or sepsis (three and six). Group 2 had a higher incidence of wound dehiscence (one) than in group 1 (none). The incidence of prolonged postoperative ileus was lower in group 1 (one vs 12), as was the length of hospital stay (31.6 days vs 22.8 days). Conclusions,Bowel preparation had no advantage for the surgical outcome but it increased the length of hospital stay. [source]


Relationship of carotenoid and vitamins A and E with the acute inflammatory response in acute pancreatitis

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 3 2000
F. J. M. Curran
Background: Inflammation and oxidative stress are believed to be important in the development of the systemic complications of acute pancreatitis. The fat-soluble vitamins A and E, and the carotenoids have antioxidant properties. The aim of this study was to assess the effect of acute pancreatitis on serum concentrations of vitamin antioxidants and to relate such changes to the degree of the inflammatory response. Methods: Thirteen consecutive patients with predicted severe acute pancreatitis were compared with 26 matched healthy controls. Five patients developed severe acute pancreatitis and three of these died. Vitamin antioxidant and C-reactive protein (CRP) levels were measured daily for up to 7 days. Results: Patients had significantly lower levels of antioxidants throughout the course of the study (P < 0·017). In patients there was a significant correlation between peak CRP and trough antioxidant levels (P < 0·01). In patients with mild acute pancreatitis, the concentrations of retinol and ,-carotene at final review were significantly higher than those in patients with severe acute pancreatitis (P < 0·05). This coincided with a reduction in CRP level. Conclusion: In acute pancreatitis, circulating concentrations of vitamin antioxidants are reduced and are inversely related to the rise in CRP level. © 2000 British Journal of Surgery Society Ltd [source]


Capillary haemangioma of the eyelids and orbit: a clinical review of the safety and efficacy of intralesional steroid

ACTA OPHTHALMOLOGICA, Issue 3 2003
Michael O'Keefe
Abstract. Purpose:, To describe the presenting features, investigations, treatment and outcome of a series of patients with capillary haemangioma of the eyelids and orbit. Methods:, A retrospective analysis of 21 patients, presenting between the years 1985 and 2000. Effectiveness of treatment was determined by final visual acuity and cosmetic result. Results:, Lesions were more common in females and the upper eyelid was a definite site of predilection. A total of 87.5% of lesions presented within 6 weeks of birth. Intralesional steroid injections were received by 79% of patients. Amblyopia was a definite complication. No local or systemic complications were associated with intralesional steroid injection. Surgery and laser treatment were reserved for persistent lesions. Conclusion:, Early recognition and prompt treatment with intralesional steroid prevents early occlusion amblyopia, but follow-up and management of refractive amblyopia with glasses and patching is necessary in the longer term. In this series, intralesional steroid proved to be a safe effective treatment. [source]


Anatomical variations and clinical implications of the artery to the lingual nerve

CLINICAL ANATOMY, Issue 4 2003
Stanton D. Harn
Abstract The pterygomandibular space is a critical anatomic area for the delivery of local anesthesia in the practice of dentistry. The neurovascular contents of this area are subject to trauma and its resultant local and systemic complications. This study of 202 cadaveric specimens reaffirms the literature as to the percent distributions of the superficial and deep routes of the maxillary artery and details for the first time the anatomic variations of the artery to the lingual nerve. This artery courses through the pterygomandibular space placing it at risk for injection trauma along with the other neurovascular contents. It has been uncommonly identified and referred to in the literature, yet it may be the first artery encountered when entering the space with a needle or during surgical intervention in the area.

DOSE,RESPONSE OF ROPIVACAINE ADMINISTERED CAUDALLY TO CHILDREN UNDERGOING SURGICAL PROCEDURES UNDER SEDATION WITH MIDAZOLAM

CLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, Issue 7 2004
F Tonatiu Aguirre-Garay
SUMMARY 1.,In a double-blind randomized controlled design, 50 children were allocated to receive bupivacaine 0.25% or ropivacaine 0.25%, 0.32%, 0.40% or 0.50% by caudal block. 2.,Caudal block was performed after induction of anaesthesia with 2,5% sevoflurane, atropine 10 µg/kg and midazolam 100,300 µg/kg. During the surgical procedure, patients were maintained under spontaneous ventilation and no intravenous or inhalatory anaesthetic agent was administered. For transoperative sedation, midazolam 100,300 µg/kg was administered every 0.5,1.0 h. Transoperative cardiovascular response, postoperative analgesia and local and systemic complications were evaluated. 3.,Groups were similar (P > 0.05) in sex, age, weight and in the time elapsed from caudal block to the beginning of the surgical procedure. The surgical time was significantly lower in the ropivacaine 0.25% group. The duration of analgesia was 24 h with ropivacaine 0.25% and approximately 10 h in the other four groups (P < 0.001). Linear regression analysis revealed a significant relationship between the postoperative analgesic period produced by ropivacaine and the surgical time (r = , 0.48, two-sided P = 0.002). Systolic and diastolic blood pressures remained in the physiologically normal range for the duration of the transoperative period. Vomiting was present in only one patient receiving ropivacaine 0.50%. 4.,In children, the duration of analgesia produced by caudal block with ropivacaine may be affected by surgical time. At surgical times of 0.5,1 h, ropivacaine 0.25% produced at least 24 h postoperative analgesia. At similar surgical times, ropivacaine 0.32%, 0.40% and 0.50% produced similar analgesic times to bupivacaine 0.25%. [source]
