Tympanic membrane rupture following general anesthesia with nitrous oxide: a case report.
نویسنده
چکیده
Although rare, tympanic membrane rupture during general anesthesia with nitrous oxide has been reported previously in the literature. Nitrous oxide administration and the effects on closed body cavities will be reviewed. Key factors in patient assessment which can determine safe use of nitrous oxide in the clinical setting will also be discussed.

UNLABELLED The nitrous oxide is an inhaling gas that can increase intratympanic pressure during the anesthetic act and cause negative pressure after it is discontinued, mainly in patients with Eustachian tube dysfunction. These pressure variations may come up with clinical implications such as tympanic membrane rupture, ossicular system disarticulation, haemotympanum, barotraumas, prosthesis di...
متن کاملThermoregulatory vasoconstriction during propofol/nitrous oxide anesthesia in humans: threshold and oxyhemoglobin saturation.
To determine the thermoregulatory effects of propofol and nitrous oxide, we measured the threshold for peripheral vasoconstriction in seven volunteers over a total of 13 study days. We also evaluated the effect of vasoconstriction on oxyhemoglobin saturation (SpO2). Anesthesia was induced with an intravenous bolus dose of propofol (2 mg/kg), followed by an infusion of 180 micrograms.kg-1 x min-...

trisiiicate is not now the alkali of choice, but there are alternatives. I believe that metoclopramide, by increasing lower oesophageal sphincter tone, hastening gastric emptying and preventing vomiting, is an appropriate drug to use. These young women are usually otherwise healthy, often undergoing an investigative procedure. It is imperative that the anaesthetic technique is designed to keep ...
متن کاملClinical and MRI manifestations of nitrous oxide induced vitamin B12 deficiency: A case report
A 50 year-old man was referred with history of acute ataxia and lower extremity paresthesia 10 days after general anesthesia with nitrous oxide. Cervical MRI showed long hypersignal lesion in posterior segment of the cord. Blood analysis revealed vitamin B12 deficiency. Nitrous oxide-induced myelopathy should be considered in patients who develop acute neurological manifestation after general a...
متن کاملNitrous oxide-induced slow and delta oscillations
OBJECTIVES Switching from maintenance of general anesthesia with an ether anesthetic to maintenance with high-dose (concentration >50% and total gas flow rate >4 liters per minute) nitrous oxide is a common practice used to facilitate emergence from general anesthesia. The transition from the ether anesthetic to nitrous oxide is associated with a switch in the putative mechanisms and sites of a...
