Spinal motor evoked potentials (SMEP) were recorded from tibialis anterior muscle after epidural stimulation of the spinal cord at the low cervical or high thoracic level during scoliosis surgery. By using a double stimulus pulse to produce temporal summation within the spinal cord a maximal CMAP response was readily achieved despite good surgical(More)
This study examined the hypothesis that headache after general anesthesia is related to a caffeine withdrawal state. Two hundred eighty-seven patients undergoing minor elective procedures under general anesthesia were studied. Four to six hours after anesthesia each patient completed a questionnaire assessing his or her own alcohol, tobacco, and caffeine(More)
PURPOSE Epidural cannulation is a difficult technique in the patient undergoing scoliosis repair, due to axial rotation of the vertebral bodies, as well as angulation of the spinal processes. This case series was performed to investigate whether ultrasonography could facilitate epidural insertion in patients with scoliosis, by assessing the degree of(More)
Posterior spinal fusion for correction of scoliosis is a major procedure for which the provision of satisfactory, safe postoperative analgesia is often a problem. One possible solution involves the placement of epidural catheters under direct vision by the surgeon at the end of the procedure, followed by an epidural infusion of local anaesthetic with or(More)
We performed a double-blind, placebo-controlled study to evaluate the different methods of administering droperidol in patients using patient-controlled analgesia (PCA) with morphine. Eighty patients undergoing major orthopedic procedures received temazepam 0.2 mg/kg orally followed by induction of general anesthesia with propofol 2.5 mg/kg, fentanyl 2(More)
We present the anaesthetic and surgical management, and post-operative course of a patient with osteogenesis imperfecta which exemplifies the problems associated with this condition. The observed petechial haemorrhagic rash is not characteristic of the bleeding tendency in osteogenesis imperfecta nor characteristic of acute disseminated intravascular(More)
Midazolam was used for anaesthesia in 20 patients undergoing cardioversion; 10 received flumazenil, which caused immediate rapid reversal of anaesthesia, and these patients maintained SpO2 greater than 95%, breathing air, within 5-10 min. In contrast, patients in the placebo group were still partially sedated and required oxygen therapy for up to 2 h to(More)
The somatosensory evoked potential (SEP) recorded from the cervical epidural space in response to stimulation of the posterior tibial nerve is often used to monitor spinal cord integrity during scoliosis surgery. Epidural analgesia may be used as part of the anesthetic technique for scoliosis surgery, but the effects of the local analgesic on the evoked(More)
