In this prospective study, we evaluated the bispectral index (BIS) and postoperative recall during the intraoperative wake-up examination in 34 children and adolescents undergoing scoliosis surgery. Each anesthesiologist was blinded to BIS values throughout surgery and the wake-up test. The BIS, mean arterial blood pressure, and heart rate were compared ...

Due to its hemodynamic properties and ease of administration (quick induction, rare cough or laryngospasm), Sevoflurane has rapidly become the agent of induction of choice in pediatric patients. However, it can induce troublesome excitation phenomena during induction and awakening and it could have an epileptogenic effect. The mechanisms and strategies ...

BACKGROUND: A retrospective review of shoulder procedures using scalene block anesthesia was performed. METHODS: The records of all 218 patients who had undergone scalene block anesthesia over a three-year period at two facilities were retrospectively reviewed. All blocks were performed with use of a standard blunt-needle technique with the patient ...

Myotonic dystrophy presents several problems to the anaesthetist. We describe what we believe to be the first report of target-controlled sedation combined with regional anaesthesia in a patient with myotonic dystrophy. Precise control of propofol levels and titration to patient satisfaction avoided the problem of delayed recovery which has been ...

BACKGROUND AND OBJECTIVE: Midazolam may occasionally precipitate hostility and violence instead of tranquility. We characterized these episodes, their rate of occurrence, the potential paradoxical responders and possible predisposing circumstances among patients undergoing lower body surgery under spinal or epidural anaesthesia and midazolam sedation. PATIENTS AND METHODS: Fifty-eight patients who fulfilled ...

Patient-controlled sedation (PCS) has been used for extracorporeal shock wave lithotripsy (SWL) because it allows for rapid individualized titration of anesthetics. Because of its sedating effects, the addition of propofol to remifentanil may improve patient tolerance of SWL with PCS. One hundred twenty patients were randomly assigned to receive remifentanil ...

The aim of this pilot study was to investigate anxiety levels in patients undergoing elective caesarean section under regional anaesthesia, and to ascertain whether this group of patients considered the administration of anxiolytic premedicant drugs before surgery acceptable. Anxiety was assessed by two means, using a self-reported anxiety score and ...

None of the equations frequently used to predict body surface area (BSA) has been validated for obese patients. We applied the principles of body size scaling to derive an improved equation predicting BSA solely from a patient's weight. Forty-five patients weighing from 51.3 to 248.6 kg had their height and ...

Morphine is the preferred analgesic agent for the critically ill patient. Fentanyl is the preferred analgesic agent for critically ill patients with hemodynamic instability or for patients manifesting symptoms of histamine release with morphine or morphine allergy. Hydromorphone is an acceptable alternative to morphine for patients with significant adverse affects ...

BACKGROUND: Propofol is commonly used to provide anaesthesia for children undergoing oesophagogastroduodenoscopy (OGD). Despite this, the plasma concentration-response relationships for propofol used in this setting have not been established. METHODS: In order to determine the EC50 of propofol during OGD, we studied 12 children aged 3-10 years. No premedication was ...

Cessation of IV patient-controlled analgesia (PCA) in the postoperative period is often an arbitrary clinical decision. We conducted a prospective survey of patients 24 h after cessation of IV PCA morphine to determine whether they wished to be restarted on PCA, and to evaluate factors affecting this decision. One hundred ...

Esophagogastroduodenoscopy (EGD) is useful in the diagnosis and evaluation of dyspepsia. We investigated factors that might be associated with self-reported patient tolerance of EGD and therefore might serve as objective, reliable and useful surrogates for self-reported patient tolerance. We also investigated factors that might influence EGD tolerance. We prospectively evaluated ...

While under hypnosis, patients can be taught to alter their psychophysiological functions. With this ability to alter these functions, patients can overcome the anxiety associated with surgery. Patients with high anxiety often experience more depression, can have increased complications, need more anesthesia and medication, have suppressed immune function, and often ...

Recovery from anesthesia might be compromised in obese patients. Because of its pharmacological properties, desflurane might allow rapid postoperative recovery for these patients. We compared postoperative recovery for 36 obese patients randomized to receive either desflurane, propofol, or isoflurane to maintain anesthesia during laparoscopic gastroplasties. Anesthesia was induced with propofol ...

There is little experience of anaesthesia for patients with Huntington's chorea. These patients have an increased risk of intraoperative complications such as pulmonary aspiration. We present the successful anaesthetic management of a 17-yr-old patient suffering from Huntington's chorea requiring urgent appendectomy. After rapid-sequence induction with thiopental 400 mg and succinylcholine ...

Obesity is associated with physiological changes that can alter the pharmacokinetic parameters of many drugs. Vancomycin and the aminoglycosides are the only antibacterials that have been extensively investigated in the obese population. The apparent volume of distribution (Vd) and total body clearance of vancomycin are increased in obese patients and ...

The safety and effectiveness of patient-controlled propofol sedation was prospectively assessed in 18 healthy, phobic dental patients. Using a randomised, crossover design each patient received two sessions of equivalent dental treatment under patient-controlled or clinician-controlled propofol sedation. The patient-controlled technique used 29.8% less drug (time-weighted dose) than the clinician-controlled method ...

The effects of patient habitus (e.g., breast attenuation in women and diaphragmatic attenuation in men) have long been recognized as factors that reduce the accuracy of myocardial perfusion imaging. Although it has long been assumed that patient obesity effects accuracy, this has never been formally evaluated. We studied the effects ...
