Retrospective analysis of risk factors and predictors of intraoperative complications in neuraxial blocks at Faculdade de Medicina de Botucatu-UNESP.

Background And Objectives: Cardiovascular changes associated with neuraxial blocks are a cause of concern due to their frequency and because some of them can be considered physiological effects triggered by the sympathetic nervous system blockade. The objective of this study was to evaluate intraoperative cardiovascular complications and predictive factors associated with neuraxial blocks in patients ≥ 18 years of age undergoing non-obstetric procedures over an 18-year period in a tertiary university hospital--HCFMB-UNESP.

Methods: A retrospective analysis of the following complications was undertaken: hypertension, hypotension, sinus bradycardia, and sinus tachycardia.

[The use of dexmedetomidine in neurosurgery.].

Background And Objectives: The use of alpha2-adrenergic agonists is increasingly more frequent in Anesthesiology, as adjuvant or the sole anesthetic drug. Currently, dexmedetomidine is gaining popularity due to its greater selectivity for the alpha2-adrenergic receptors and its pharmacokinetic profile. The aim of this review was to analyze the use of dexmedetomidine in neurosurgery.

The early systemic and gastrointestinal oxygenation effects of hemorrhagic shock resuscitation with hypertonic saline and hypertonic saline 6% dextran-70: a comparative study in dogs.

The smaller volemic state from hypertonic (7.5%) saline (HS) solution administration in hemorrhagic shock can determine lesser systemic oxygen delivery and tissue oxygenation than conventional plasma expanders. In a model of hemorrhagic shock in dogs, we studied the systemic and gastrointestinal oxygenation effects of HS and hyperoncotic (6%) dextran-70 in combination with HS (HSD) solutions in comparison with lactated Ringer's (LR) and (6%) hydroxyethyl starch (HES) solutions.

Preoperative combined with intraoperative skin-surface warming avoids hypothermia caused by general anesthesia and surgery.

Study Objectives: To evaluate the effects of intraoperative skin-surface warming with and without 1 hour of preoperative warming, in preventing intraoperative hypothermia, and postoperative hypothermia, and shivering, and in offering good conditions to early tracheal extubation.

Design: Prospective, randomized, blind study.

Setting: Teaching hospital.
