Randomized Controlled Trial Clinical TrialAbsence of explicit and implicit memory in unconscious patients using a TCI of propofol.
Episodes of implicit memory have been described during propofol anaesthesia. It remains unclear whether implicit memory is caused by short periods of awareness or occurs in an unconscious subject. ⋯ In our group of young ASA I/II patients, in the absence of any noxious stimulus, no implicit or explicit memory was found when the calculated concentration of propofol using a Diprifusor was maintained at the level associated with LOC.

Comparative StudyComparison of transcutaneous and endtidal CO2-monitoring for rigid bronchoscopy during high-frequency jet ventilation.
To compare endtidal and transcutaneous respiratory monitoring of high-frequency jet ventilation (HFJV) in rigid bronchoscopy. Both techniques provide a noninvasive measurement of pCO2. ⋯ Endtidal capnography offers accurate respiratory monitoring of HFJV. Transcutaneous monitoring showed a good correlation to ABG only during steady-state conditions. For the dynamic phase the accuracy was significantly lower. Thus, we cannot recommend transcutaneous respiratory monitoring for the specific indication of rigid bronchoscopy using HFJV.

Randomized Controlled Trial Comparative Study Clinical TrialContinuous spinal anesthesia/analgesia vs. single-shot spinal anesthesia with patient-controlled analgesia for elective hip arthroplasty.
In total hip replacement surgery several anesthesiological techniques can be used. In this study we compared continuous spinal anesthesia (CSA) and postoperative analgesia vs. single-shot spinal anesthesia (SPA) and postoperative patient-controlled intravenous analgesia with morphine (SPA). ⋯ Continuous spinal anesthesia/analgesia is a very practicable method providing better postoperative analgesia and better hemodynamic stability during anesthesia induction than SPA followed by morphine PCA analgesia after total hip replacement surgery.

Randomized Controlled Trial Comparative Study Clinical TrialDexamethasone is as effective as ondansetron for the prevention of postoperative nausea and vomiting following breast surgery.
Postoperative nausea and vomiting remain a common problem following breast surgery. This study assesses whether dexamethasone is as effective as ondansetron in the control of postoperative nausea and vomiting (PONV). ⋯ Ondansetron 4 mg or dexamethasone 4 mg are equally effective in the prevention of postoperative nausea and vomiting following breast surgery. Other factors being similar, the difference in cost between these drugs would favor the use of dexamethasone instead of ondansetron when monotherapy against PONV is used.
