The first intravenous anaesthetic: how well was it managed and its potential realized?

Our speciality commonly traces its origin to a demonstration of the inhalation of ether by a patient undergoing surgery in Boston in 1846. Less well known is the demonstration of the i.v. injection of opium with alcohol into a dog in Oxford in 1656, leading to anaesthesia followed by full long-term recovery. After gaining i.v. access, a mixture of opium and alcohol was injected, resulting in a brief period of anaesthesia. After a period during which the dog was kept moving to assist recovery, a full recovery was made. Details from this momentous experiment allow us to compare the technique used with modern management. It is important to consider why there was a failure to translate the results into clinical practice and nearly 200 yr of potentially pain-free surgery. Possible factors include lack of equipment for i.v. access, lack of understanding of dose–response effects, and a climate of scientific discovery rather than clinical application. Given the current interest in total i.v. a

Efficacy of intravenous dexamethasone to reduce incidence of postoperative sore throat: A prospective randomized controlled trial

   Abstract   Background: Sore throat and hoarseness are common complications of endotracheal intubation. It may be very distressing for the patient and may lead to sleep disturbances and unpleasant memories. Materials and Methods: This prospective double-blinded randomized control trial was aimed to determine the efficacy of prophylactic intravenous dexamethasone to reduce the incidence of postoperative sore throat at 1 hour after tracheal extubation. Ninety six patients of either sex aged between 18 to 60 years scheduled for elective surgeries needing general anesthesia with endotracheal intubation, were randomly allocated into two groups A and B. The patients received either intravenous 0.2 mg/kg dexamethasone (group A, n = 48) or normal saline (group B, n = 47) just before induction. Trachea was intubated with appropriate size disposable endotracheal tubes for securing the airway. Follow up for the incidence of sore throat, cough and hoarseness was done at 1,

Brief Preoperative Smoking Abstinence: Is There a Dilemma?

Brief Preoperative Smoking Abstinence: Is There a Dilemma?  AuthorsYu Shi, MD, MPH andDavid O.

Address e-mail to warner.david@mayo.edu. Abstract The concern that stopping smoking shortly (<8 weeks) before surgery increases postoperative pulmonary complications poses a barrier to tobacco use interventions in surgical patients. We show how this concern arose from a misinterpretation of initial studies and has remained in the medical literature despite the accumulation of later evidence. The persistence of unsubstantiated concepts is not uncommon and can have a significant impact on medical practice. Although it may take several weeks to derive pulmonary benefit from quitting, fear of an increase in pulmonary complications should not be a barrier for clinicians to help their patients quit smoki

Neuraxial anesthesia has opioid-sparing effects and may provide better postoperative recovery to patients when compared with general anesthesia. Our main objective in this study was to compare th
