Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical Trial
Comparison of cisatracurium-induced neuromuscular block at the masseter and adductor pollicis muscle.
Adequate relaxation of the masseter muscle is important during endotracheal intubation and for the patency of a patient's airway during recovery from anaesthesia. We evaluated onset and recovery from cisatracurium-induced neuromuscular block at the masseter and adductor pollicis muscles. Thirty patients were randomly allocated to receive either 0.1 or 0.15 mg kg(-1) cisatracurium. ⋯ In the 0.15 mg kg(-1) cisatracurium group recovery of T1 to 75% of control and to a TOF-ratio of 0.7 occurred sooner at the masseter (P < 0.05). We conclude that onset and recovery from cisatracurium neuromuscular block occurs more rapidly at the masseter than at the adductor pollicis. It appears unlikely that residual paralysis is present at the masseter once neuromuscular function at the adductor pollicis has completely recovered.

Randomized Controlled Trial Comparative Study Clinical Trial
Double-blind randomized study of tramadol vs. paracetamol in analgesia after day-case tonsillectomy in children.
Fifty children (2-9 years) scheduled for tonsillectomy were enrolled in a double-blind randomized prospective study to compare postoperative analgesia provided with propacetamol/paracetamol (acetaminophen) or tramadol. A standard anaesthetic technique was used; each patient received sufentanil 0.25 microg kg(-1) intravenously followed with either i.v. propacetamol 30 mg kg(-1) or tramadol 3 mg kg(-1) before surgical incision. For postoperative analgesia, each child received either tramadol drops (2.5 mg kg(-1)) or paracetamol (acetaminophen) suppositories (15 mg kg(-1)), 6 and 12 h after surgery the first day and three times a day during postoperative days 2 and 3. ⋯ Rescue medication consisted of i.v. diclofenac (1 mg kg(-1)) during the first six postoperative hours and oral ibuprofen (6-9 mg kg(-1)) afterwards. Postoperative pain scores (Children's Hospital of Eastern Ontario Pain Scale) in recovery, numerical pain scale in the ward and at home, and rescue analgesic use were significantly lower in the tramadol group. No serious adverse effects were observed.
