Randomized Controlled TrialEffect of intraoperative personalized goal-directed hemodynamic management on acute myocardial injury in high-risk patients having major abdominal surgery: a post-hoc secondary analysis of a randomized clinical trial.
Acute myocardial injury is common after noncardiac surgery and associated with mortality. Impaired intraoperative cardiovascular dynamics are a risk factor for acute myocardial injury. Optimizing intraoperative cardiovascular dynamics may thus reduce acute myocardial injury. ⋯ Acute myocardial injury occurred in 4 of 90 patients (4%) in the personalized goal-directed hemodynamic management group and in 12 of 90 patients (13%) in the routine hemodynamic management group (relative risk: 0.33, 95% confidence interval: 0.11 to 0.99, P = 0.036; absolute risk reduction: - 9%, 95% confidence interval: - 17% to - 0.68%, P = 0.034). In this post-hoc secondary analysis, intraoperative personalized goal-directed hemodynamic management reduced the incidence of acute myocardial injury compared to routine hemodynamic management in high-risk patients having major abdominal surgery. This needs to be confirmed in larger prospective trials.

Randomized Controlled TrialAn optimal tracheal tube preshaping strategy for endotracheal intubation using video laryngoscopy: a randomized controlled trial.
Although video laryngoscopy solves the problem of glottis exposure, it is difficult to deliver the tube to the glottic opening when the tracheal tube is unevenly shaped. This study aimed to compare the effects of different tube shapes on the first-pass success (FPS) rate in patients undergoing video laryngoscopy-assisted tracheal intubation. Three hundred patients above 18 years of age who underwent general anaesthesia and required endotracheal intubation were included in the study. ⋯ And the time to tracheal intubation in Group C was significantly less than that in Group A and Group B (22.21 ± 4.01 vs. 19.92 ± 4.11 vs. 17.71 ± 3.47; P < 0.001). The straight-to-cuff stylet preshape angulation of curvature of the blade could provide a higher FPS rate and shorter time to tracheal intubation during video laryngoscopy-assisted endotracheal intubation. Trial registration: Chinese Clinical Trial Registry, ChiCTR1900026019.

Randomized Controlled TrialEvaluation of indigenously developed closed-loop automated blood pressure control system (claps): a preliminary study.
Closed-loop systems have been designed to assist anesthetists in controlling anesthetic drugs and also maintaining the stability of various physiological variables in the normal range. In the present study, we describe and clinically evaluated a novel closed-loop automated blood pressure control system (CLAPS) in patients undergoing cardiac surgery under cardiopulmonary bypass. Forty ASA II-IV adult patients undergoing elective cardiac surgery were randomly allocated to receive adrenaline, noradrenaline, phenylephrine and nitroglycerine (NTG) adjusted either through CLAPS (CLAPS group) or manually (Manual group). ⋯ The cardiac index and left ventricular end-diastolic area were comparable between the groups. Automated infusion of vasoactive drugs using CLAPS is feasible and also better than manual control for controlling hemodynamics during cardiac surgery. Trial registration number and date This trial was registered in the Clinical Trial Registry of India under Registration Number CTRI/2018/01/011487 (Retrospective; registration date; January 23, 2018).

Continuous hemoglobin measurement during frontal advancement operations can improve patient outcomes.
Massive hemorrhage in pediatric cranioplasty operations may necessitate blood transfusion, which may cause many complications. Radical-7 Pulse CO-Oximeter (Massimo Corporation, Irvine, CA) can provide continuous hemoglobin concentration (SpHb) measurements noninvasively. In this study, we aimed to evaluate the effects of SpHb measurement on perioperative transfusion management and postoperative patient outcomes. ⋯ There was a positive correlation between the amount of PRBC transfusion and the length of ICU stay (r = 0.459, P = 0.003). Patients with perioperative continuous SpHb measurement have lower intraoperative PRBC transfusion, less postoperative bleeding, and shorter ICU stay. When necessary, SpHb, together with clinical judgment and laboratory confirmation, can be used in decision-making for perioperative PRBC transfusion.
