Sedation during spinal anaesthesia: a case for the routine administration of oxygen.
We have studied the effect of sedation with midazolam on arterial oxygen saturation during spinal anaesthesia in two groups of patients: one group received supplementary oxygen, the other group breathed room air. A significant reduction in oxygen saturation was observed in patients not receiving supplementary oxygen; six of 15 patients in this group developed hypoxaemia or severe hypoxaemia whi...
متن کاملSedation during spinal anaesthesia in infants.
BACKGROUND Neuraxial anaesthesia in adults decreases the dose of i.v. or inhalational anaesthetic needed to reach a desired level of sedation. Furthermore, spinal anaesthesia alone has a sedative effect. The mechanism behind this phenomenon is presumed to be decreased afferent stimulation of the reticular activating system after sympatholysis. We hypothesized that this mechanism is equally acti...
متن کاملComparison of the i.v. administration of midazolam and diazepam as sedation during spinal anaesthesia.
Midazolam hydrochloride and diazepam in emulsion were compared as i.v. sedatives for spinal anaesthesia. Mean doses of midazolam 12 mg and diazepam 27 mg were required to induce sleep and provide good or adequate sedation throughout surgery of approximately 1 h duration. Neither drug caused loss of the airway or significant cardiorespiratory changes. The frequency of drowsiness after operation ...
متن کاملInadvertent administration of 100% oxygen during anaesthesia.
Sir,—Modern anaesthetic machines have a device (usually referred to as "the oxygen bypass" or "emergency oxygen") which enables the anaesthetist to administer high flows of 100% oxygen. When a patient is connected to an anaesthetic machine it is possible to overlook the fact that the emergency oxygen device is in the "on" position and is delivering 100% oxygen. This occurrence is most likely if...
متن کاملSedation during spinal anaesthesia: comparison of propofol and midazolam.
Propofol and midazolam were compared in 40 patients undergoing orthopaedic surgery under spinal anaesthesia. An infusion of either 1% propofol or 0.1% midazolam was given at a rate adjusted to maintain a similar level of sedation. The mean time to reach this required level was similar in both groups. Quality and ease of control of sedation were good in all patients. A mean infusion rate of 3.63...
