Randomized Controlled TrialThe Effects of Programmed Intermittent Paravertebral Bolus Infusion on Postoperative Analgesia in Patients Undergoing Video-Assisted Thoracoscopic Surgery: A Prospective, Randomized, Controlled Study.
To compare the effects of programmed intermittent bolus infusion (PIBI), continuous thoracic paravertebral infusion (CTPI), and continuous intravenous infusion (CII) on postoperative analgesia in patients undergoing video-assisted thoracoscopic surgery (VATS). ⋯ PIBI outperformed CTPI and CII in inducing analgesia for postoperative pain in patients undergoing VATS.

Observational StudyLeft Ventricular Ejection Fraction Correlation With Stroke Volume as Estimated by Doppler Echocardiography in Cardiogenic Shock: A Retrospective Observational Study.
Echocardiography is the main tool for cardiac assessment and helps to guide management in patients admitted to the intensive care unit (ICU) with cardiogenic shock (CS). Left ventricular ejection fraction (LVEF) is a commonly used echocardiographic surrogate for left ventricular (LV) systolic function. In this hypothesis-generating study, the authors investigated the correlation between LVEF and stroke volume (SV)/SV index (SVI) estimated by Doppler echocardiography in patients admitted to the ICU with CS and reduced LVEF. ⋯ There is a weak correlation between LVEF and SV or SVI estimated by Doppler echocardiography in patients admitted to the ICU with STEMI complicated by CS and reduced LVEF. Visually estimated LVEF correlated slightly better with Doppler SV compared to modified Simpson's LVEF.

Pain Trajectories After Valve Surgeries Performed via Midline Sternotomy Versus Mini-Thoracotomy.
Controlling moderate-to-severe pain remains a major challenge after cardiothoracic surgery. Several outcomes have been compared extensively after valve surgery performed via midline sternotomy versus mini-thoracotomy, but postoperative pain (POP) was not adequately examined. Therefore, the authors tested the hypothesis that there is no difference in POP trajectories in patients undergoing valve surgery via midline sternotomy versus mini-thoracotomy. ⋯ Midline sternotomies are associated with higher odds of having an acute worsening or stationary versus a rapidly improving pain trajectory compared to mini-thoracotomies. Therefore, the choice of incision may play an important role in determining POP trajectory after valve surgery.
