Review Meta Analysis Comparative StudyIntermittent epidural bolus compared with continuous epidural infusions for labor analgesia: a systematic review and meta-analysis.
Intermittent epidural bolus when compared with continuous epidural infusion for labour analgesia results in slightly reduced local anaesthetic use and a small improvement in maternal satisfaction. Caesarean section and instrumental delivery rates were not significantly statistically different.

Review Meta AnalysisDexamethasone to prevent postoperative nausea and vomiting: an updated meta-analysis of randomized controlled trials.
Dexamethasone provides effective PONV prophylaxis (NNT 3.7). There is however no benefit of an 8 to 10 mg IV dose over a lower 4 to 5 mg dose.

Case ReportsCase report: ultrasound-guided continuous thoracic paravertebral block for outpatient acute pain management of multilevel unilateral rib fractures.
A 61-year-old man with multiple unilateral rib fractures (T3-T8) gained the ability to breathe deeply and to ambulate after ultrasound-guided continuous thoracic paravertebral block and was discharged home after being observed for 15 hours after the block. The ultrasound guidance was helpful in determining the site of rib fractures and the optimal level for catheter placement. This report also discusses the management of analgesia using continuous paravertebral block in an outpatient with trauma.

Beat-to-beat tracking of systolic blood pressure using noninvasive pulse transit time during anesthesia induction in hypertensive patients.
Pulse transit time (PTT) has been reported to show good agreement with arterial blood pressure (BP) in awake humans. We evaluated whether noninvasive beat-to-beat PTT accurately correlated with invasively measured continuous arterial BP during anesthesia induction in hypertensive patients. ⋯ Beat-to-beat PTT was fairly well correlated with invasive systolic BP and could predict a reduction in systolic BP during anesthesia induction. Beat-to-beat PTT may show potential as a useful noninvasive index of systolic BP when invasive BP is unavailable in high-risk hypertensive patients.
