Randomized Controlled TrialEfficacy of Ultrasound-Guided Transversus Thoracic Muscle Plane Block on Postoperative Opioid Consumption After Cardiac Surgery: A Prospective, Randomized, Double-Blind Study.
The postoperative analgesic efficacy of transversus thoracic muscle plane block (TTMPB) has not yet been evaluated sufficiently. This randomized controlled study evaluated the effect of TTMPB on postoperative opioid consumption in patients undergoing cardiac surgery. ⋯ A single preoperative TTMPB provided effective analgesia and decreased opioid requirements in patients undergoing cardiac surgery.

Randomized Controlled TrialCPAP Effects on Oxygen Delivery in One-Lung Ventilation During Minimally Invasive Surgical Ablation for Atrial Fibrillation in The Supine Position.
In minimally invasive surgical ablation for atrial fibrillation during video-assisted thoracoscopy surgery, one-lung ventilation (OLV) with a double- lumen tube is commonly employed. In contrast with the majority of thoracic procedures, the patient lies supine; thus, the protective effect of gravity is lost and intrapulmonary shunt remains high. To decrease intrapulmonary shunt and to increase oxygenation, many strategies are utilized: high inspiratory fraction of oxygen (FIO2), positive end-expiratory pressure on the ventilated lung, and continuous positive airway pressure (CPAP) on the deflated lung. ⋯ During OLV for atrial fibrillation surgical ablation in the supine position, CPAP on the deflated lung seemed to be ineffective to reduce Qs/Qt or to increase arterial partial pressure of oxygen and DO2I, provided cardiac output was maintained above 1.5 L/min/m2.

Randomized Controlled TrialContinuous Magnesium Infusion to Prevent Atrial Fibrillation After Cardiac Surgery: A Sequential Matched Case-Controlled Pilot Study.
The authors aimed to test whether a bolus of magnesium followed by continuous intravenous infusion might prevent the development of atrial fibrillation (AF) after cardiac surgery. ⋯ The magnesium delivery strategy was associated with a decreased incidence of postoperative AF in cardiac surgery patients. These findings provide a rationale and preliminary data for the design of future randomized controlled trials.
