چکیده
In a field trial of 1,257 patients receiving methoxyflurane, trichloroethylene, and nitrous-oxide/oxygen for the relief of pain in labour methoxyflurane has been shown to have certain advantages which support its use in midwifery practice. The trial confirms our objective method for screening an inhalational agent as an obstetric analgesic.

Methoxyflurane and nitrous oxide as obstetric analgesics. II. A comparison by self-administered intermittent inhalation.
Methoxyflurane (0.35%) in air and nitrous oxide/oxygen (50%/50%) self-administered intermittently in the usual way have been compared as analgesics for labour. There were 25 patients in each group. Objective assessment by an anaesthetist showed that methoxyflurane is the more effective analgesic, and this was supported by the opinion of the multiparae. Nausea and vomiting were significantly les...
متن کاملMethoxyflurane in Dental Anaesthesia: a Blind Trial by R. D. Unkles and J. I. Murray Lawson
Anaesthesia with nitrous oxide and oxygen, alone or supplemented with methoxyflurane or halothane, was administered for dental extractions in 256 patients (204 children and 52 antenatal women). Anaesthesia was regarded as "good" in 69 per cent of patients with methoxyflurane and 75 per cent with halothane, but only 50 per cent with unsupplemented nitrous oxide and oxygen. A further trial was ca...
متن کاملManagement of trauma pain in the emergency setting: low-dose methoxyflurane or nitrous oxide? A systematic review and indirect treatment comparison
Background Low-dose methoxyflurane and nitrous oxide (N2O; 50:50 with oxygen) are both self-administered, self-titrated, rapid-acting, nonnarcotic, and noninvasive inhalational agents with similar onset times of pain relief. The aim of this review was to compare the clinical efficacy, safety, and tolerability of these analgesics in emergency care. Materials and methods A systematic literature...
متن کاملThe effect of inhalational anaesthetics on hypoxic pulmonary vasoconstriction and pulmonary vascular resistance in the perfused lungs of the dog and cat.
Alveolar hypoxia produced an increase in pulmonary vascular resistance in isolated cat and dog lungs or lobes perfused at constant flow. This response was abolished for varying periods of time by the administration of high concentrations of inhalational anaesthetic agents. In these preparations 5 per cent halothane caused pulmonary vasodilatation whereas 15 per cent ether, 1.5 per cent trichlor...
متن کاملTechniques of inhalational analgesia in the postoperative period.
Subanaesthetic concentrations of ether, trichloroethylene, cyclopropane and nitrous oxide can provide analgesia (Dundee, Nicholl and Black, 1962). This property of ether (Artusio, 1955) and cyclopropane (Sheiner, 1958) has been applied to the production of analgesia for surgical procedures but only nitrous oxide and trichloroethylene have been used for postoperative analgesia. Nitrous oxide has...
