Randomized Controlled Trial Clinical TrialLow-dose ketamine infusion for analgesia during postoperative ventilator treatment.
In a randomized, double-blind study with placebo, ketamine was used as an analgesic during ventilator treatment in the period of recovery after major abdominal surgery. Forty patients were orally intubated and ventilated by means of a volume-controlled ventilator. Twenty of them received an i.v. bolus of 30 mg of ketamine followed by an 8-h infusion of 1 mg per minute. ⋯ Dreams and hallucinations were recalled in three patients in the control group and five in the ketamine group. Only one control and two ketamine patients experienced these as unpleasant. In this investigation, ketamine infusion in a low dose appeared to offer satisfactory analgesia and to permit tolerance of the orotracheal tube.

Work practices relating to intubation and associated procedures in intensive care units in Sweden.
A survey into the current usage of tracheal tubes and associated procedures, such as various sedation regimes and antacid therapy, in intensive care units was carried out in Sweden by sending a questionnaire to physicians in charge of intensive care units in 70 acute hospitals which included seven main teaching hospitals. The purpose of the survey was to see how far the recent advances in tube and cuff design and awareness of the problems caused by prolonged therapeutic paralysis in intensive care units have influenced the attitudes and work practices of physicians in Sweden. Forty-nine replies were received (a 70% response rate). ⋯ The majority of units rarely used muscle relaxants. Phenoperidine and diazepam were the most popular drugs used for the sedation technique. 71.4% of teaching hospitals and 40.9% of non-teaching hospitals used antacids routinely in patients on intermittent positive pressure respiration. The results are discussed.
