Randomized Controlled Trial Clinical TrialA small dose of droperidol decreases postoperative nausea and vomiting in adults but cannot improve an already excellent patient satisfaction.
We evaluated whether or not 1) a routine prophylaxis with 20 microg x kg(-1) body weight of droperidol would efficiently prevent postoperative nausea and vomiting (PONV) after elective surgery in adults and 2) an efficient prophylaxis would improve patient satisfaction. ⋯ Routine PONV prophylaxis with 20 microg x kg(-1) body weight of droperidol is cost-efficient and appropriate in women but not in men.

Clinical TrialChanges in circulating blood volume after infusion of hydroxyethyl starch 6% in critically ill patients.
The cardiovascular response to a volume challenge with hydroxyethyl starch (HES) (200/0.5) 6% depends on the relation between the volume of HES 6% infused and the expansion of the blood volume in critically ill patients. However, only relatively limited data exist on the plasma expanding effect of infusion of HES 6% in critically ill patients. The purpose of the study was to evaluate the variation in the expansion of the circulating blood volume (CBV) in critically ill patients after infusion of 500 ml of colloid (HES (200/0.5) 6%) using the carbon monoxide method. ⋯ The large interindividual variation of the volume expansion after infusion of HES 6% in critically ill patients illustrates one of the difficulties in optimizing colloid therapy and interpretating the changes in hemodynamic variables after a colloid challenge.

Case ReportsOne way to ventilate patients during fibreoptic intubation.
Occasionally anaesthesiologists find themselves in situations where ventilation during intubation with a fibreoptic bronchoscope (FOB) is desirable. In order to ventilate the patient during the FOB intubation, we used a 90 degree angle swivel connector, normally used for fibreoptic bronchoscopia in an intubated patient. ⋯ The method has been used in 7 patients who were impossible to intubate with a conventional procedure. In all patients ventilation was possible and intubation was performed in 5 min (range 1-15).

Randomized Controlled Trial Comparative Study Clinical TrialPatient-controlled epidural analgesia versus continuous epidural analgesia after total knee arthroplasty.
Patient-controlled epidural analgesia (PCEA) has been found to be an effective method for pain relief during labour and after surgery. The goal of this study was to compare the efficacy of bupivacaine-fentanyl PCEA and continuous epidural infusion with the same mixture for treatment of pain after total knee arthroplasty. ⋯ The amount of bupivacaine-fentanyl solution consumed was significantly less with PCEA than with continuous infusion of bupivacaine-fentanyl solution without affecting the quality of postoperative analgesia after total knee arthroplasty. Several of the elderly patients had difficulties in operating the PCEA apparatus.

Randomized Controlled Trial Comparative Study Clinical TrialTotal knee replacement: a comparison of ropivacaine and bupivacaine in combined femoral and sciatic block.
Femoral and sciatic nerve block may improve post-operative analgesia following total knee replacement. ⋯ Femoral and sciatic blockade following intrathecal bupivacaine/diamorphine provided superior analgesia when compared with intrathecal bupivacaine/diamorphine alone. There were no significant clinical differences between the group receiving bupivacaine 7.5 mg x ml(-1) and the group receiving ropivacaine 7.5 mg x ml(-1).
