In the Intraoperative Hypothermia for Aneurysm Surgery Trial, neither systemic hypothermia nor supplemental protective drug affected short- or long-term neurologic outcomes of patients undergoing temporary clipping.
Early postoperative complications following neurosurgical proceduresPurpose: To assess the incidence and characteristics of early postoperative complications in patients following neurosurgical procedures. Methods: All patients undergoing neurosurgery during a four month period were followed postoperatively for up to four hours in the post anesthetic care unit or intensive care unit. Patient information and all complications were documented by the investigators on a standardized form. Complications were classified as respiratory, cardiovascular, nausea and vomiting, shivering and other. Risk factors analyzed for the occurrence of complications included age, sex, ASA status, type of surgery, elective or emergency surgery and postoperative placement. Results: Four hundred eighty six adult patients were followed, but in 55 patients the trachea remained intubated during the four hour study period and they were eliminated from the analysis of postoperative complications. At least one complication occurred in 54.5% of the remaining 431 patients. Respiratory problems occurred in 2.8%, trauma to the airway in 4.4%, cardiovascular complications in 6.7%, neurological in 5.7% and nausea and/or vomiting in 38%. The highest incidence of patients with complications was during spine (65%) and vascular (66%) surgery, compared with tumour (47%) and other (43%) surgery, P < 0.05. Other risk factors included age < 70 yr for nausea and vomiting (P < 0.02), and elective surgery for spine and vascular surgery (P < 0.001 ). Conclusion: There was a high incidence of early postoperative complications in neurosurgical patients. The most common problem was nausea and vomiting especially in the younger patient undergoing elective spine surgery.Objecdf: I~valuer les caract&istiques et I'incidence de complications postop&atoires pr&oces chez des patients qui ont subi une intervention neurochirurgicale. M~.thode : Pendant quatre mois, tousles patients qui avaient subi une neurochirurgie ont &~ suivis, pendant une p&iode pouvant aller jusqu'~, quatre heures, ~ la salle de r6veil ou ~ I'unit~ des soins intensifs. Les chercheurs ont not~ sur un formulaire standardis6 les informations recueillies aupr& du patient et routes les complications. Ces derni&es ont Et6 class~es en complications respiratoires, cardiovasculaires, nausEes et vomissements, frissons et autres. Les facteurs de risques analys~s selon la survenue des complications comprenaient I'~ge, le sexe, 1'6tat ASA, le type de chirurgie, I'aspect prEvisible ou non de la chirurgie et le placement postop6ratoire. REsultats 9 Quatre cent quatre-vingt six patients adultes ont &6 suivis, mais on a exclu 55 patients de I'analyse des complications postop&atoires puisqu'ils ont eu besoin d'intubation pendant les quatre heures de I'exp&ience. Une complication au moins est survenue chez 54,5 % des 431 autres patients. Des complications respiratoires sont survenues chez 2,8 % des patients, cardiovasculaires chez 6,7 %, neurologiques chez 5,7 %; un traumatisme des voies a&iennes chez 4,4 % et des naus...
The risks of regional anesthesia most commonly disclosed to patients by academic regional anesthesiologists and regional anesthesia fellows are benign in nature and occur frequently. Severe complications of regional anesthesia are far less commonly disclosed. The incidences of severe complications disclosed by academic regional anesthesiologists and their fellows can be inconsistent with those cited in the contemporary literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
