Frequency of using nitrous oxide (N2O) in anesthetic field decreased recently by the influence of the environmental problems and the widespread use of intravenous agents. In dental treatment, however, inhalation sedation using low concentration of N2O has been effectively used to relax dental patients. Nitrous oxide inhalation sedation for dental treatment generally involves the use of a combination of low-dose N2O and high-dose oxygen. ⋯ Also, high-dose oxygen would contribute to manage "(pre) syncope" due to pain stimuli. Thus, N2O inhalation sedation is effective for the dental treatment, although the leak of N2O affects the health of dental staffs. The present review described the advantage and harmful effects of N2O in dental management.

Sodium bicarbonate has been standard therapy for the treatment of acidosis. In lactic acidosis and hypercapnic acidosis, however, there is no clinical data supporting its effectiveness. We reviewed the literature of the efficacy of sodium bicarbonate on lactic acidosis and hypercapnic acidosis. ⋯ Conversely, acidosis or hypercapnia might be protective in acute lung and systemic organ injury. Therefore, the unprepared use of bicarbonate might be harmful in terms of fluid and sodium overload and excess lactate concentrations. According to current literature, we cannot recommend sodium bicarbonate administration for patients with lactic acidosis and hypercapnic acidosis.

Bad anesthesia management easily causes mal-temperature situation. Main consequence of it is hypothermia as defined core temperature less than 36 degrees C and the other one is hyperthermia. ⋯ Other than that, hypothermia may provoke many complications after surgery including higher rate of wound infection, longer duration of hospitalization, more morbid cardiac events, prolongation of drug effects, more postoperative shivering, and delayed post anesthetic recovery. This review article discusses the mal-temperature management during surgery.
