Randomized Controlled Trial Comparative StudyDural Puncture Epidural Technique Improves Labor Analgesia Quality With Fewer Side Effects Compared With Epidural and Combined Spinal Epidural Techniques: A Randomized Clinical Trial.
The dural puncture epidural (DPE) technique is a modification of the combined spinal epidural (CSE) technique, where a dural perforation is created from a spinal needle but intrathecal medication administration is withheld. The DPE technique has been shown to improve caudal spread of analgesia compared with epidural (EPL) technique without the side effects observed with the CSE technique. We hypothesized that the onset of labor analgesia would follow this order: CSE > DPE > EPL techniques. ⋯ Analgesia onset was most rapid with CSE with no difference between DPE and EPL techniques. The DPE technique has improved block quality over the EPL technique with fewer maternal and fetal side effects than the CSE technique for parturients requesting early labor analgesia.

Randomized Controlled TrialA Randomized Controlled Trial of Music Use During Epidural Catheter Placement on Laboring Parturient Anxiety, Pain, and Satisfaction.
Although music is frequently used to promote a relaxing environment during labor and delivery, the effect of its use during the placement of neuraxial techniques is unknown. Our study sought to determine the effects of music use on laboring parturients during epidural catheter placement, with the hypothesis that music use would result in lower anxiety, lower pain, and greater patient satisfaction. ⋯ Music use during epidural catheter placement in laboring parturients is associated with higher postprocedure anxiety and no improvement in pain or satisfaction; however, a stronger desire for music with future epidural catheter placements was observed. Further investigation is needed to determine the effect of music use in parturients requesting and using epidural labor analgesia.

Randomized Controlled TrialIntraperitoneal Instillation of Lidocaine Improves Postoperative Analgesia at Cesarean Delivery: A Randomized, Double-Blind, Placebo-Controlled Trial.
Cesarean delivery is a commonly performed procedure worldwide. Despite improvements in balanced multimodal analgesia, there remains a proportion of women for whom postoperative pain relief and patient satisfaction are still inadequate. Intraperitoneal instillation of local anesthetic has been shown to be effective in reducing postoperative pain after abdominal surgery. We sought to investigate the effect of intraperitoneal instillation of lidocaine on postcesarean delivery pain as part of a multimodal analgesia regimen. ⋯ The use of intraperitoneal instillation of lidocaine improves early postoperative pain management after cesarean delivery. Furthermore, it reduces the number of women requesting systemic opioids in the immediate postpartum period. Women undergoing peritoneal closure may particularly benefit from this intervention.

Randomized Controlled TrialImproving Prediction of Postoperative Myocardial Infarction With High-Sensitivity Cardiac Troponin T and NT-proBNP.
This study sought to determine whether preoperatively measured high-sensitivity cardiac troponin T (hs-cTnT) and N-terminal pro-brain natriuretic peptide (NT-proBNP) improve cardiac risk prediction in patients undergoing major noncardiac surgery compared with the standard risk indices. ⋯ The addition of cardiac biomarkers hs-cTnT and NT-proBNP to RCRI improves the prediction of adverse cardiac events in the immediate postoperative period after major noncardiac surgery. The high negative predictive value of preoperative hs-cTnT and NT-proBNP suggest usefulness as a "rule-out" test to confirm low risk of postoperative MI.

Randomized Controlled TrialProgrammed Intermittent Epidural Bolus for Labor Analgesia During First Stage of Labor: A Biased-Coin Up-and-Down Sequential Allocation Trial to Determine the Optimum Interval Time Between Boluses of a Fixed Volume of 10 mL of Bupivacaine 0.0625% With Fentanyl 2 μg/mL.
Most studies that have compared programmed intermittent epidural bolus (PIEB) with continuous epidural infusion regimens have included patient-controlled epidural analgesia and/or manual bolus as rescue analgesia for breakthrough pain. Consequently, the optimal time interval between PIEB is yet to be determined. We designed a study to establish the optimal time interval between PIEB of 10 mL of bupivacaine 0.0625% with fentanyl 2 μg/mL to produce effective analgesia in 90% of women during first stage of labor without breakthrough pain. ⋯ The optimal time interval between PIEB of 10 mL of bupivacaine 0.0625% with fentanyl 2 μg/mL is approximately 40 minutes. Further studies to determine the efficacy of this regimen throughout the entire duration of labor are warranted.
