Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of ondansetron and prochlorperazine for the prevention of nausea and vomiting after tympanoplasty.
To evaluate the effects on PONV and headache after tympanoplasty of prochlorperazine 0.2 mg.kg-1 i.m., ondansetron 0.06 mg.kg-1 i.v. or placebo (isotonic saline) 0.02 ml.kg-1 i.v. given immediately after induction of anaesthesia prior to tracheal intubation. ⋯ Prophylactic prochlorperazine 0.2 mg.kg-1 i.m. and ondansetron 0.06 mg.kg-1 i.v. are similarly efficacious in reducing nausea with vomiting after tympanoplasty, while prochlorperazine 0.1 mg.kg-1 i.v. is less efficacious. Neither drug given as described appeared to reduce the frequency of postoperative nausea alone or vomiting alone.

Randomized Controlled Trial Clinical Trial
Dorsal penile nerve block in children undergoing circumcision in a day-care surgery.
Circumcision is performed under general anaesthesia (GA) with dorsal penile nerve block (DPNB) as an analgesic technique for postoperative pain. The purpose of this study was to compare DPNB as the sole anaesthetic procedure vs GA and DPNB for circumcision in children as an outpatient procedure. ⋯ These data confirm that DPNB has advantages over GA + DPNB for paediatric circumcision in day-care surgery.

Randomized Controlled Trial Clinical Trial
Evaluation of cisatracurium, a new neuromuscular blocking agent, for tracheal intubation.
The primary objective of this study was a blinded, randomized comparison of the recommended intubating dose of atracurium (0.5 mg. kg-1) with an approximately equipotent dose of cisatracurium (0.1 mg. kg-1) during N2O/O2/propofol/fentanyl anaesthesia. ⋯ The intubation results reported in this study together with the combination of predictable recovery from neuromuscular block and apparent haemodynamic stability make cisatracurium a potentially useful muscle relaxant in clinical practice.

Randomized Controlled Trial Clinical Trial
Wound infiltration with lidocaine prolongs postoperative analgesia after haemorrhoidectomy with spinal anaesthesia.
There are few clinical data examining whether sensitization of peripheral nerves contributes to postoperative pain when the entry of noxious impulses to the central nervous system is blocked. We hypothesized that wound infiltration with lidocaine would provide better postoperative analgesia than with normal saline following haemorrhoidectomy with spinal blockade. ⋯ Preoperative lidocaine infiltration to the surgical area provided prolonged postoperative analgesia in patients receiving haemorrhoidectomy with spinal anaesthesia.

Sciatic nerve block in the popliteal fossa (popliteal nerve block, PNB) is an anaesthetic technique well-suited for operations below the knee. However, difficulty with positioning the patient in the prone position often precludes the classical, posterior approach to the block. In this report, an alternative approach to PNB that can easily be performed with a patient in the supine position is described. ⋯ The supine approach to PNB allows the use of the block in patients that cannot be positioned in the prone position. Flexion of the leg at the knee greatly facilitates identification of the anatomical landmarks. When combined with a block of the femoral or saphenous nerve, this technique provides excellent anaesthesia for patients undergoing foot and ankle surgery.
