Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of lysine acetylsalicylate and oxycodone in postoperative pain following upper abdominal surgery.
Intravenous lysine acetylsalicylate (LAS) and oxycodone were compared under double-blind conditions for analgesia after upper abdominal surgery in sixty patients anaesthetized by N2O--O2--halothane--relaxant technique. Either 125 mg/10 kg or 250 mg/10 kg LAS or 0.4 mg/10 kg or 0.8 mg/10 kg oxycodone was randomly administered when the patients complained of moderate or severe postoperative pain. When 30 min had elapsed following the injection of the test drug, oxycodone was given in 4 mg increments on demand until adequate pain relief was achieved. ⋯ However, LAS had a slower onset of action. Sweating seemed to occur more frequently after LAS than oxycodone, but significant changes in respiratory rate or sedation following LAS-oxycodone combinations when compared to oxycodone alone were not noted. The results show that for analgesia after upper abdominal surgery, 1.8 g of LAS may be substituted for about 6 mg of oxycodone.

This study presents a series of 38 patients in whom total hip replacement was performed by using a hypotensive anaesthetic technique with moderate haemodilution. 17 patients operated on during normotension without haemodilution served as controls. Halothane, d-tubocurarine and pentolinium tartrate were the agents used. During the operation circulation was monitored carefully. ⋯ No complications attributable to the hypotensive technique occurred. The results suggest that the hypotensive anaesthetic technique with haemodilution reduces the need for blood transfusion in major surgery. However, only patients in good cardiovascular status are suitable for this technique, and careful monitoring of the circulation is mandatory during the anaesthesia.

Comparative Study
Segmental epidural analgesia and postpartum sequelae.
The incidence of the postpartum sequelae of headache, backache, pain in the legs and difficulties in micturiton, was studied in 219 normal vaginal deliveries. 135 of the parturients received continuous segmental epidural analgesia at the level of Th 10--12 for pain relief during the first stage of labour. The remaining 84 parturients served as controls. The results showed that segmental epidural analgesia did not increase the occurrence of postpartum sequelae either in primiparous or in multiparous parturients.

Comparative Study Clinical Trial Controlled Clinical Trial
Comparison of muscle relaxants in clinical use.
A prospective clinical comparison of d-tubocurarine, alcuronium, gallamine and pancuronium was performed in 400 surgical patients. Various parameters usually followed during clinical anaesthesia were recorded from the beginning of, to the recovery from anaesthesia. Endotracheal intubation was performed with or without suxamethonium. ⋯ Pancuronium and alcuronium caused least changes in the cardiovascular parameters. Erythematous skin reactions were seen mostly after the use of d-tubocurarine and suxamethonium. This could depend on histamine liberating potency of these muscle relaxants.

Forty-five patients with multiple injuries treated at an intensive care unit were studied prospectively. The patients were divided into two groups: the severely injured (no mortality) and critically injured (56% mortality). Treatment was started within two hours from the accident in all cases. ⋯ The factor V and fibrinogen levels were initially lowered. Low platelet values at 2-4 days, prolonged thrombin and r-times, secondary decrease of fibrinogen FV, FVIII, and low Thrombotest values suggested disseminated intravascular coagulation associated with complications, such as fat embolism and "shock lung" syndromes. General bleeding tendency with high mortality was observed in 16% of the patients.
