Red Blood Cell Transfusion and Surgical Site Infection After Colon Resection Surgery: A Cohort Study.
Surgical site infections (SSIs) after colon surgery remain a critical safety issue. Patients with an SSI have an increased risk of death, prolonged hospitalization, and increased costs of care. Red blood cell (RBC) transfusion is given during the perioperative period to increase blood oxygen delivery, but it is associated with complications, including infection. We hypothesized that RBC transfusion would be associated with increased SSI risk in patients undergoing colon resection surgery. ⋯ RBC transfusion has no apparent association with increased risk for incisional SSIs, but may be associated with increased risk for organ space SSI and septic shock after colon resection surgery.

Paravertebral Block Does Not Reduce Cancer Recurrence, but Is Related to Higher Overall Survival in Lung Cancer Surgery: A Retrospective Cohort Study.
Postoperative analgesic methods are suggested to have an impact on long-term prognosis after cancer surgery through opioid-induced immune suppression. We hypothesized that regional analgesia that reduces the systemic opioid requirement would be related to lower cancer recurrence and higher overall survival compared to intravenous patient-controlled analgesia (PCA) for lung cancer surgery. ⋯ Pain-control methods are not related to cancer recurrence. However, PVB may have a beneficial effect on overall survival of patients with lung cancer.

Observational StudyMortality, Geriatric, and Nongeriatric Surgical Risk Factors Among the Eldest Old: A Prospective Observational Study.
Preoperative risk and postoperative outcomes among the elderly are the subject of extensive debate. However, the eldest old, that is, the fastest-growing and most vulnerable group, are insufficiently studied; even their mortality rate is unclear. This prospective observational study was performed with the aim of determining the mortality rate of this population and establishing which preoperative conditions were predictors of which postoperative outcomes. The study was undertaken between 2011 and 2015 in a major tertiary care university hospital. ⋯ The eldest old is a distinct group with a considerable mortality rate and their own particular risk factors. Surgical complexity and certain geriatric variables (malnutrition and frailty), which are overlooked in American Society of Anesthesiologists and most other usual scores, are particularly relevant in this population. Inclusion of these factors along with appropriate comorbidities for risk stratification should guide better decision making for families and doctors alike and encourage preoperative optimization of patients.

Review Meta AnalysisAssociation of STOP-Bang Questionnaire as a Screening Tool for Sleep Apnea and Postoperative Complications: A Systematic Review and Bayesian Meta-analysis of Prospective and Retrospective Cohort Studies.

Randomized Controlled TrialEffects of Esmolol on the Esophagogastric Junction: A Double-Blind, Randomized, Crossover Study on 14 Healthy Volunteers.
Passive regurgitation may occur throughout the perioperative period, increasing the risk for pulmonary aspiration and postoperative pulmonary complications. Hypnotics and opioids, especially remifentanil, that are used during anesthesia have been shown to decrease the pressure in the esophagogastric junction (EGJ), that otherwise acts as a barrier against passive regurgitation of gastric contents. Esmolol, usually used to counteract tachycardia and hypertension, has been shown to possess properties useful during general anesthesia. Like remifentanil, the β-1-adrenoreceptor antagonist may be used to attenuate the stress reaction to tracheal intubation and to modify perioperative anesthetic requirements. It may also reduce the need for opioids in the postoperative period. Its action on the EGJ is however unknown.The aim of this trial was to compare the effects of esmolol and remifentanil on EGJ pressures in healthy volunteers, when administrated as single drugs. ⋯ Esmolol, compared with remifentanil, does not affect EGJ function. This may be an advantage regarding passive regurgitation and esmolol may thus have a role to play in anesthesia where maintenance of EGJ barrier function is of outmost importance.
