Early recovery of tricuspid annular isovolumic acceleration after mitral valve surgery – an observational study
Conclusion Persistent, significant depression of longitudinal markers of RV function despite functional improvement (discharge from hospital) make it difficult to assess recovery during the early perioperative period. Isovolumic acceleration, a load-independent measure of contractility, might be a more reliable measure of early recovery in RV function in this patient population.

Breath alcohol of anesthesiologists using alcohol hand gel and the “five moments for hand hygiene” in routine practice
Conclusion Anesthesia practitioners using alcohol hand gel in a manner that conforms with recommended hand hygiene can test positive for alcohol on a breathalyzer assay. Positive tests probably arose from inhalation of alcohol vapour into the respiratory dead space following gel application. If workplace breath testing for alcohol is implemented, it should be completed more than 15 min after applying alcohol hand gel. Positive results should be verified with a BAC test.

Bronchial blocker versus left double-lumen endotracheal tube in video-assisted thoracoscopic surgery: a randomized-controlled trial examining time and quality of lung deflation
Abstract Introduction Double-lumen endotracheal tubes (DL-ETT) and bronchial blockers (BB) have both been used for lung isolation in video-assisted thoracic surgery (VATS). Though not well studied, it is widely thought that a DL-ETT provides faster and better quality lung collapse. The aim of this study was to compare a BB technique vs a left-sided DL-ETT strategy with regard to the time and quality of lung collapse during one-lung ventilation (OLV) for elective VATS. Methods Forty patients requiring OLV for VATS were randomized to receive a BB (n = 20) ...

Perioperative complications in adults with a posterior mediastinal mass: a retrospective observational cohort study
Abstract Background We studied the incidence of perioperative complications in patients presenting with a posterior mediastinal mass and the possible predictors of complications in these patients. Methods We conducted a review of the perioperative records of patients aged over 18 years with a posterior mediastinal mass confirmed by computed tomography (CT) who were admitted for surgical procedures relating to the mass during 2004-2014. Perioperative complications were defined as 1) hypoxemia (pulse oximetry 40 cm H2O or respiratory acidosis with P...

A systematic review of transthoracic and transesophageal echocardiography in non-cardiac surgery: implications for point-of-care ultrasound education in the operating room
Conclusion In this systematic review examining the use of TTE or TEE in non-cardiac surgery, the most frequent diagnoses were valvulopathy, low LVEF, hypovolemia, PE, SWMAs, and RV failure. This information should be used to inform evidence-based curricula for POCU in anesthesiology. (Source: Canadian Journal of Anesthesia)

Prewarming neurosurgical patients to minimize hypotension on induction of anesthesia: a randomized trial
Abstract Purpose Prewarming prior to surgery is effective in preventing perioperative hypothermia. There is a paucity of evidence, however, regarding the hemodynamic effects of prewarming. We hypothesized that the nadir mean arterial pressure during anesthesia induction would be higher after prewarming than after no prewarming. Methods We randomized 32 patients prior to elective neurosurgery to receive either one hour of forced-air convective warming at 46°C or routine care (full body blanket with convective warmer attached but not turned on). All pa...

Perioperative management and oncological outcomes following radical cystectomy for bladder cancer: a matched retrospective cohort study
Abstract Purpose The immune system plays an important role in tumour progression. Systemic opioids are immunosuppressive; thus, theoretically they may promote tumour spread. Our primary aim was to test the hypothesis that general anesthesia (GA) with spinal analgesia (SA) in patients with bladder cancer undergoing radical cystectomy (RC) will both reduce systemic opioid use and improve oncological outcomes. Since blood transfusions also induce immunosuppression, a secondary aim was to evaluate the effect of perioperative transfusions on oncological outcomes. Metho...

The objective of this study was to describe changes in cerebral tissue oxygen saturation (SctO2) due to changes in body position in healthy volunteers and in patients undergoing surgery under general anesthesia in the beach chair position (BCP) and lateral decubitus position (LDP). Methods In this prospective observational study, SctO2 was measured in 85 awake volunteers serially positioned every 15 min, beginning with the supine position (SP) and followed by the beach chair, supine, and lateral decubitus positions. Cerebral tissue oxygen saturation was also measured supine and in ei...

Epidural analgesia does not increase the rate of inpatient falls after major upper abdominal and thoracic surgery: a retrospective case-control study
Abstract Purpose Postoperative epidural analgesia for major upper abdominal and thoracic surgery can provide significant benefits, including superior analgesia and reduced pulmonary dysfunction. Nevertheless, epidural analgesia may also be associated with decreased muscle strength, sympathetic tone, and proprioception that could possibly contribute to falls. The purpose of this retrospective case-control study was to search a large national database in order to investigate the possible relationship between postoperative epidural analgesia and the rate of inpatient falls. ...

Abstract Background It remains unclear whether the opioid-sparing effects of dexmedetomidine seen in patients undergoing general anesthesia are reproducible in patients undergoing spinal anesthesia. We hypothesized that the administration of intravenous dexmedetomidine for sedation during total knee arthroplasty under spinal anesthesia would decrease postoperative morphine consumption in the first 24 hr following surgery. Methods We conducted this prospective double-blind randomized-controlled trial in 40 patients (American Society of Anesthesiologists p...

Can anesthetic-analgesic technique during primary cancer surgery affect recurrence or metastasis?
Conclusions Current laboratory research suggests that perioperative interventions may impact recurrence or metastasis through effects on cancer cell signalling, the immune response, or modulation of the neuroendocrine stress response. Further evidence is awaited from prospective randomized-controlled trials. Meanwhile, with limited data upon which to make strong recommendations, anesthesiologists should seek optimal anesthesia and analgesia for their patients based on individual risk-benefit analysis and best available evidence on outcomes other than cancer recurrence.
