Randomized Controlled Trial Clinical TrialComparative effect of 6% hydroxyethyl starch (containing 1% dextrose) and lactated Ringer's solution for cesarean section under spinal anesthesia.
This study aimed to compare low-molecular weight hydroxyethyl starch containing 1% dextrose (HES) infusion and lactated Ringer's solution (LR) in the prevention of hypotension associated with spinal anesthesia for cesarean section. ⋯ This study did not show an advantage of HES compared with LR in the prevention of hypotension or in the reduction of ephedrine dose during cesarean section under spinal anesthesia. The anesthesia level, rather than the choice of intravenous fluid solution, might be related to the ephedrine dose.

Prevention and treatment of malignant hyperthermia in certified training hospitals in Japan: a questionnaire.
To assess the preparedness of hospitals in Japan for cases of malignant hyperthermia (MH). ⋯ The results of the survey revealed that some hospitals had inadequate monitoring methods and a lack of prepared dantrolene for cases of MH under general anesthesia. We recommend that essential monitors be deployed and adequate preparations of dantrolene be maintained for effective early diagnosis and treatment of MH.

Suppressive effect of spinal dorsal-horn neuronal activity by local spinal-cord cooling is reversed by naloxone in cats.
The purpose of this study was to assess the effect of local spinal cord cooling on spinal dorsal-horn neuronal activity, with special emphasis on the role of endogenous opioid. ⋯ The results demonstrate that endogenous opioids may play an important role in dorsal-horn neuronal suppression induced by local spinal-cord cooling.

An investigation was made of the population and function of lymphocytes in canine peripheral blood, in animals with or without laparotomy under inhalation anesthesia. ⋯ These results indicate that surgical trauma concomitant with anesthesia could impair immunocompetence by reducing the number and function of lymphocytes.
