Observational StudyThoracic trauma and acute respiratory distress syndrome in polytraumatized patients admitted to a level I trauma center: a retrospective analysis.
Although thoracic trauma has often been associated with the development of acute respiratory distress syndrome (ARDS) in general, its impact on ARDS in combination with severe concomitant injuries has still to be elucidated. Therefore, the objective of this study was to determine the frequency of thoracic trauma and ARDS in polytraumatized patients, and to evaluate the impact of thoracic trauma on the occurrence and the onset of ARDS. ⋯ Thoracic trauma was identified as major risk factor for ARDS occurrence and earlier onset in polytrauma victims.

Mechanical ventilation is a cornerstone of the intraoperative management of the surgical patient and is still mandatory in several surgical procedures. In the last decades, research focused on preventing postoperative pulmonary complications (PPCs), both improving risk stratification through the use of predictive scores and protecting the lung adopting so-called protective ventilation strategies. The aim of this review was to give an up-to-date overview of the currently suggested intraoperative ventilation strategies, along with their pathophysiologic rationale, with a focus on challenging conditions, such as obesity, one-lung ventilation and cardiopulmonary bypass. ⋯ Due to the high number of surgical procedures performed daily, the impact on patients' health and healthcare costs can be relevant, even when new strategies result in an apparently small improvement of outcome. A protective intraoperative ventilation should include a low tidal volume of 6-8 mL/kg of predicted body weight, plateau pressures ideally below 16 cmH2O, the lowest possible driving pressure, moderate-low PEEP levels except in obese patients, laparoscopy and long surgical procedures that might benefit of a slightly higher PEEP. The work of the anesthesiologist should start with a careful preoperative visit to assess the risk, and a close postoperative monitoring.

Transportation of a patient between medical facilities without interruption of the medical treatment can be a challenging task. This review aims to define the term "interhospital transport" and give a general overview of the steps for organizing a transfer. Furthermore we discuss the team qualification, equipment standards and how to manage adverse events before and during transport by means of patient triage. ⋯ Relocation team members need a specific training that focus on typical critical events that happen during transport. Technical equipment (ventilator, stretcher, monitor, defibrillator, external pacemaker, blood-gas analyzer) facilitates smooth patient transition from one facility to a distant one. The use of checklists is associated with a reduction of incidents during the transport.

Randomized Controlled TrialUltrasound-determined landmarks decreases pressure pain at epidural insertion site in immediate postpartum period.
Women have blamed epidurals for their post-partum back pain for decades. Survey-based studies have shown similar incidence of chronic back pain between women who delivered with epidurals compared to those who did not. However, epidural insertion site pain has yet to be evaluated by a quantitative measure: pressure pain threshold (PPT). Algometer measured PPT has been shown to be accurate and reproducible in acute, chronic, and postoperative pain studies. This study determines the effect of ultrasound-based landmarks on the PPT at the epidural insertion site in the post-partum period. ⋯ We showed that epidural placed with ultrasound-determined landmarks not only improves the success of epidural placement but also minimizes the number of intervertebral levels with decreased PPT.

Comparative StudyIntraoperative dexmedetomidine sedation reduces the postoperative agitated behaviour in elderly patients undergoing orthopaedic surgery compared to the propofol sedation: a retrospective analysis of 855 patients.
Postoperative agitation or confusion is one of the symptoms of hyperactive delirium in elderly patients. We retrospectively evaluated the incidence of postoperative abnormal psychomotor behavior in elderly surgical patients according to the use of different intraoperative sedative agents: dexmedetomidine vs. propofol. ⋯ This study suggests that intraoperative dexmedetomidine sedation, as compared with propofol sedation, may have a greater beneficial effect in reducing agitated behavior in elderly patients undergoing orthopedic surgery with regional anesthesia.
