Randomized Controlled Trial Comparative Study Clinical TrialRespiratory performance after upper abdominal surgery. A comparison of pain relief with intercostal blocks and centrally acting analgesics.
The respiratory capacity was studied during the first 2 days postoperatively in 94 patients, aged 19 to 75 years and undergoing surgery through an upper abdominal incision. Postoperative pain relief was randomly administered, either by intercostal block (i.c.b.) and centrally acting analgesics on demand, or by centrally acting analgesics alone. Respiratory studies comprising forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow rate (PEF) and analysis of arterial blood gases were made. ⋯ Thus postoperative i.c.b. following cholecystectomy performed through a subcostal incision resulted in higher FVC, FEV1 and PEF values than without i.c.b. at least during the time of effective nerve block. I.c.b. after subcostal incision also improved arterial oxygen tension. The patients undergoing cholecystectomy and receiving a second i.c.b. 8 h after the first one had better respiratory function than the patients without any block during the first 2 days postoperatively.

This study aimed to establish whether it was practical to perform sciatic nerve block by the anterior approach in a group of children of different ages and weights. A total of 82 blocks were performed of which 78 (95.2%) were judged to have been successful. ⋯ There were no immediate or late complications associated with this block in any of the patients. It is concluded that the block is easy to perform and can produce reliable postoperative analgesia for most common operations on the foot and ankle in paediatric practice.

In fit unpremedicated patients undergoing minor operations and who were ambulant on the afternoon of the operations, pretreatment with magnesium sulphate given intravenously did not reduce the incidence of suxamethonium induced myalgia below that in a similar series who received no prophylactic therapy. The injection of magnesium in conscious patients is followed by unpleasant side effects.
