Several methods are reported in the literature to analyze medically undesirable events during hospital care. Each method has several limitations, so no one has been defined as the standard tool to be able to detect failure during a medical process. The aim of this study was to compare an anesthesiological perioperative checklist with traditional Regional Incident Reporting (RIR) form in detecting and describing failures. ⋯ An anesthesiological checklist compared with traditional RIR provided a more sensible and complete framework for incident analysis during the perioperative period in patients undergoing gynecological and obstetrical surgeries.

Effects of intracisternal tramadol on Cerebral and spinal neuronal cells in rat.
The aim was to investigate whether tramadol had toxic effect on cerebral neurons and/or spinal cord neurons when it was administered into the cerebrospinal fluid. Due to lipid peroxidation (LPO) and myeloperoxidation (MPO) levels are not specific predictors of neuronal damage, these biochemical markers of tissue damage were evaluated together with the histopathological findings of apoptosis. ⋯ Tramadol had no neurotoxic effect on brain and on spinal cord tissue when administered by the intracisternal route in cerebrospinal fluid in rats.

Multicenter Study Observational StudyClinical utility of preoperative screening with STOP-Bang questionnaire in elective surgery.
Obstructive sleep apnea (OSA) is a common disease which increases the risk of perioperative complications. The aim of this study is to assess the clinical utility of preoperative screening for OSA in determining the prevalence of patients at high risk of OSA in a surgical population, the incidence of difficult airway management and the incidence of perioperative complications. ⋯ In conclusion, this study demonstrates that the prevalence of high OSA risk patients in the surgical population is high. The increase in the rates of perioperative complications justifies the implementation of perioperative strategies that use the STOP-Bang as a tool for triage.

Mechanical ventilation may induce or aggravate lung injury, a phenomenon known as ventilator induced lung injury (VILI). On a macroscopic level, the effects of mechanical stress and strain on lung tissue are well described. Increased tidal volumes may lead to volutrauma, raised airway pressures may cause barotrauma and cyclic collapse and reopening of alveolar units contributes to atelectrauma. ⋯ These cells are involved in sensing and translation of mechanical stimuli into an inflammatory response. This review provides insight into current knowledge of cellular and molecular pathways during the process of pulmonary epithelial mechanosensation and mechanotransduction under different mechanical conditions. Since evidence for specific pathways is generally lacking in some fields of alveolar epithelial mechanotransduction, this article aims at providing reasonable hypothesis for further investigation.

Comparative StudyHigh-dose fibrinogen versus a clinically recommended dose of fresh frozen plasma for reversal of dilutional coagulopathy in an in vitro model of severe hemodilution.
Volume substitution using colloids and crystalloids dose-dependently induces dilutional coagulopathy. For treatment, fibrinogen concentrate and fresh frozen plasma are options, though the effective dosage of either agent is unclear. The objective of this study was to evaluate, whether high-dose fibrinogen or recommended doses of fresh frozen plasma are equally effective in reversing profound dilutional coagulopathy in vitro. ⋯ High-dose fibrinogen concentrate and clinically recommended doses of fresh frozen plasma are equally effective and can partially restore viscoelastic coagulation assays in profound saline and gelatin dilutions, but only fresh frozen plasma improves conventional coagulation assays. Hydroxyethyl starch-induced disturbance of fibrin polymerization is neither restored by fibrinogen concentrate nor fresh frozen plasma.
