Anesthesia-related mortality and morbidity over a 5-year period in 2,363,038 patients in Japan.
Statistical data of mortality and morbidity related to anesthesia have not been reported in Japan since World War II. The need to comprehensively examine the events of cardiac arrest as well as mortality prompted the first national study in Japan. ⋯ The rates in Japan of cardiac arrest and death during anesthesia and surgery due to all etiologies as well as those totally attributable to anesthesia are comparable to those of other developed countries.

Randomized Controlled Trial Clinical TrialThe effectiveness of intravenous ketamine and lidocaine on peripheral neuropathic pain.
Neuropathic pain is often severe and resistant to pharmacological treatment. The aims of the present study were to assess the analgesic effect of ketamine and lidocaine and to investigate if measurement of different variables of sensibility could be used to identify responders. We also wanted to study if treatment resulted in changes of sensibility. ⋯ Ketamine showed a significant analgesic effect. The clinical usefulness is, however, limited by disturbing side-effects.

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.

Influence of the cortical electrical activity level during general anaesthesia on the severity of immediate postoperative pain in the morbidly obese.
The objective of anaesthesia is to provide hypnosis, analgesia and adequate conditions during surgery. It is difficult to establish the appropriate dose of general anaesthetic drugs in the morbidly obese patient. Moreover, there are conflicting data concerning adequate anaesthesia levels and the severity of postoperative pain. The aim of this study was to investigate the relationship between the spectral edge frequency (SEF) during general anaesthesia and the severity of immediate postoperative pain following gastric banding surgery in morbidly obese patients. ⋯ Keeping the SEF range between 8 and 12 Hz during anaesthesia for laparoscopic gastric banding for morbid obesity, both the immediate post operative pain intensity and morphine requirement, are significantly reduced.

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.
