Prophylactic Intrathecal Morphine and Prevention of Post-Dural Puncture Headache: A Randomized Double-blind Trial.
Prophylactic intrathecal morphine does not reduce the incidence or severity of post-dural puncture headache.

Randomized Controlled Trial
Multimodal Analgesic Regimen for Spine Surgery: A Randomized Placebo-controlled Trial.
Various multimodal analgesic approaches have been proposed for spine surgery. The authors evaluated the effect of using a combination of four nonopioid analgesics versus placebo on Quality of Recovery, postoperative opioid consumption, and pain scores. ⋯ An analgesic pathway based on preoperative acetaminophen and gabapentin, combined with intraoperative infusions of lidocaine and ketamine, did not improve recovery in patients who had multilevel spine surgery.

Comment Randomized Controlled Trial Multicenter Study Comparative Study
Myocardial Function during Low versus Intermediate Tidal Volume Ventilation in Patients without Acute Respiratory Distress Syndrome.
Mechanical ventilation with low tidal volumes has the potential to mitigate ventilation-induced lung injury, yet the clinical effect of tidal volume size on myocardial function has not been clarified. This cross-sectional study investigated whether low tidal volume ventilation has beneficial effects on myocardial systolic and diastolic function compared to intermediate tidal volume ventilation. ⋯ In patients without ARDS, intermediate tidal volume ventilation decreased left ventricular and right ventricular systolic function compared to low tidal volume ventilation, although without an effect on diastolic function.
