There is little advice on the posture to be used when intubating the trachea. Does the stance used depend on experience? ⋯ Novice anaesthetists should be given explicit instructions on correct trolley height and should be taught to intubate with a straight back.

Randomized Controlled Trial Clinical Trial
Efficacy of intravenous magnesium in neuropathic pain.
Postherpetic neuralgia is a complication of acute herpes zoster characterized by severe pain and paraesthesia in the skin area affected by the initial infection. There is evidence that the N-methyl-D-aspartate receptor is involved in the development of hypersensitivity states and it is known that magnesium blocks the N-methyl-D-aspartate receptor. ⋯ The present study supports the concept that the N-methyl-D-aspartate receptor is involved in the control of postherpetic neuralgia.

Randomized Controlled Trial Comparative Study Clinical Trial
Spinal anaesthesia: comparison of plain ropivacaine 5 mg ml(-1) with bupivacaine 5 mg ml(-1) for major orthopaedic surgery.
Ropivacaine provides effective spinal anaesthesia for total hip arthroplasty. This study was designed to compare the efficacy and safety of plain ropivacaine with plain bupivacaine for spinal anaesthesia in patients undergoing total hip arthroplasty. ⋯ Intrathecal administration of either 17.5 mg plain ropivacaine or 17.5 mg plain bupivacaine was well tolerated and an adequate block for total hip arthroplasty was achieved in all patients. A more rapid postoperative recovery of sensory and motor function was seen in Group R compared with Group B.

Randomized Controlled Trial Comparative Study Clinical Trial
The laryngeal tube compared with the laryngeal mask: insertion, gas leak pressure and gastric insufflation.
We have compared the laryngeal tube and laryngeal mask in 22 patients for the success rate of insertion, gas leak pressure and the incidence of gastric insufflation. ⋯ The laryngeal tube provides a better seal in the oropharynx than the laryngeal mask.

Residual paralysis following the use of neuromuscular blocking drugs remains a clinical problem. As part of departmental quality assurance, we examined the degree of postoperative residual curarization (PORC) following atracurium. ⋯ PORC remains a clinical problem despite use of intermediate-duration neuromuscular blocking drugs and peripheral nerve stimulators. Patients undergoing procedures of short duration may be at risk of inappropriately early tracheal extubation, possibly due to work pressures. The association between suboptimal antagonism of neuromuscular blockade and short procedures needs reinforcement during postgraduate training and departmental quality assurance.
