Randomized Controlled Trial Clinical TrialAn evaluation of the efficacy of aspirin and benzydamine hydrochloride gargle for attenuating postoperative sore throat: a prospective, randomized, single-blind study.
Postoperative sore throat (POST), although a minor complication, remains a source of postoperative morbidity. We compared the efficacy of dispersible aspirin gargle to benzydamine hydrochloride (a topical nonsteroidal anti inflammatory drug) gargles for prevention of POST. We enrolled 60 consecutive female patients, 16-60 yr of age, ASA physical status I or II, undergoing elective modified radical mastectomy under general anesthesia in this prospective, randomized, placebo-controlled, single-blind study. ⋯ Aspirin gargles reduced the incidence of POST for 4 h whereas benzydamine hydrochloride gargles reduced POST for 24 h. POST was more severe in the control group at 0 and 2 h (P < 0.05). Aspirin and benzydamine hydrochloride gargles significantly reduced the incidence and severity of POST (P < 0.05).

The nature and mechanism of human consciousness is emerging as one of the most important scientific and philosophical questions of the 21st century. Disregarded as a subject of serious inquiry throughout most of the 20th century, it has now regained legitimacy as a scientific endeavor. The investigation of consciousness and the mechanisms of general anesthesia have begun to converge. In the present article I provide an introduction to the study of consciousness, describe the neural correlates of consciousness that may be targets of general anesthetics, and suggest an integrated approach to the science of consciousness and anesthesia.

Task analysis of the preincision surgical period: an independent observer-based study of 1558 cases.
Intense production pressure has focused on the preincision period (from patient-on-table to incision) as an important component of overall operating room efficiency. We conducted a prospective study in which trained independent observers measured the performance of anesthesiologists, surgeons, and nursing staff to determine anesthesia release time (ART, patient-on-table until release for surgical preparation) and surgical preparation time (SPT, start surgical preparation to incision) and the factors, including delays, that affect their duration. We enrolled 1558 patients undergoing elective surgery in a tertiary medical center. ⋯ In contrast, gender, body mass index, number of anesthesia personnel concurrently in the room, and number of rooms covered per anesthesia attending were not predictors for ART (P > 0.05). Delays affected both ART and SPT and were encountered in 24.5% of all procedures (surgery 66.8%, anesthesiology 21.7%, and logistical 11.5%). For operating room scheduling purposes, we conclude that assigning a constant fixed duration for anesthetic induction is inappropriate and will result in creating erroneous administrative expectations.
