BACKGROUND: Few adequately validated patient-reported outcome measures are available, which can assess recovery profiles following childbirth. OBJECTIVE: We aimed to determine whether quantitative recovery (using the Obstetric Quality of Recovery-10 patient-reported outcome measure) was superior following vaginal delivery compared with cesarean delivery and evaluate validity, reliability, and responsiveness of this patientreported outcome measure in the obstetrical setting in the United States. STUDY DESIGN: Women recruited into this single-center observational cohort study completed the Obstetric Quality of Recovery-10 and EuroQol 5-dimension 3L patient-reported outcome measures within 72 hours of childbirth. We assessed the validity with hypothesis testing and structural validity. In hypothesis testing, the primary outcome was Obstetric Quality of Recovery-10 scores after vaginal vs cesarean delivery. Secondary outcomes were differences in Obstetric Quality of Recovery-10 scores for vaginal delivery following induction of labor vs spontaneous labor and scheduled vs unplanned cesarean delivery, correlation with clinical parameters (American Society of Anesthesiologists classification grade, body mass index, length of hospital stay, estimated blood loss, transfusion requirement, antiemetic use, and neonatal intensive care unit admission), and qualitative ranking of Obstetric Quality of Recovery-10 items for each delivery mode. Structural validity was assessed by determining the correlation of the Obstetric Quality of Recovery-10 scores with the EuroQol 5-dimension 3L and global health visual analog scale scores. Reliability was assessed using Cronbach alpha and inter-item correlation of Obstetric Quality of Recovery-10 items. Responsiveness was assessed by evaluating the change in Obstetric Quality of Recovery-10 scores over the 72-hour postpartum period. RESULTS: Data from 215 women were analyzed. In hypothesis testing, the median (interquartile range) Obstetric Quality of Recovery-10 scores were higher following vaginal delivery than cesarean delivery (86 [77e94] vs 77 [64e86], respectively; P<.001). Multivariate model demonstrated that Obstetric Quality of Recovery-10 scores were significantly lower after cesarean delivery when adjusting for American Society of Anesthesiologists classification grade, age, body mass index, and ethnicity (R¼À8.97; P<.001). Obstetric Quality of Recovery-10 scores were similar between induction of labor and spontaneous labor, and scheduled cesarean delivery and unplanned cesarean delivery. Obstetric Quality of Recovery-10 was correlated with length of hospital stay (R¼À0.248; P<.001), estimated blood loss (R¼À0.3429; P<.001), transfusion requirement (R¼À0.140; P¼.041), and antiemetic use (R¼À0.280; P<.001). The highest ranked Obstetric Quality of Recovery-10 items were ability to hold baby, feeling in control, and ability to look after personal hygiene. The lowest ranked items were pain and shivering. In structural validity, correlation of Obstetric Quality of Recovery-10 score wa...

BACKGROUND: For emergent intrapartum cesarean delivery (CD), the literature does not support the use of any particular local anesthetic solution to extend epidural analgesia to cesarean anesthesia. We hypothesized that 3% chloroprocaine (CP) would be noninferior to a mixture of 2% lidocaine, 150 µg of epinephrine, 2 mL of 8.4% bicarbonate, and 100 µg of fentanyl (LEBF) in terms of onset time to surgical anesthesia. METHODS: In this single-center randomized noninferiority trial, adult healthy women undergoing CD were randomly assigned to epidural anesthesia with either CP or LEBF. Sensory blockade (pinprick) to T10 was established before operating room (OR) entry for elective CD. On arrival to the OR, participants received the epidural study medications in a standardized manner to simulate the conversion of “epidural labor analgesia to surgical anesthesia.” The primary outcome was the time to loss of touch sensation at the T7 level. A noninferiority margin was set at 3 minutes. The secondary outcome was the need for intraoperative analgesia supplementation. RESULTS: In total, 70 women were enrolled in the study. The mean onset time to achieve a bilateral sensory block to touch at the T7 dermatome level was 655 (standard deviation [SD] = 258) seconds for group CP and 558 (269) seconds for group LEBF, a difference in means of 97 seconds (90% confidence interval [CI], SD = −10.6 to 204; P = .10 for noninferiority). The upper limit of the 90% CI for the mean difference exceeded the prespecified 3-minute noninferiority margin. There was no meaningful difference in the requirement for intraoperative analgesia between the 2 groups. CONCLUSION: Both anesthetic solutions have a rapid onset of anesthesia when used to extend low-dose epidural sensory block to surgical anesthesia. Data from the current study provide insufficient evidence to confirm that CP is noninferior to LEBF for rapid epidural extension anesthesia for CD, and further research is required to determine noninferiority.

Background: Dexmedetomidine (Dex) has been used as an adjuvant in transversus abdominis plane (TAP) blocks. This meta-analysis was aimed at evaluating the effect of Dex in TAP blocks. Objectives: Outcome measures were total opiate consumption in 24 hours after surgery, time to systemic rescue analgesia, pain scores after surgery, and adverse events (AEs). Materials and Methods: Randomized controlled trials comparing Dex with local anesthetics to local anesthetics alone for analgesia after abdominal surgeries were included. Standardized mean difference (SMD) and mean difference (MD) were used for continuous variables and odds ratio for frequency data. Results: Analysis of data from 9 randomized controlled trials (598 patients) showed that the addition of Dex to LAs decreased opiate use in 24 hours after surgery (SMD, −3.07; 95% confidence interval [CI], −4.78 to −1.35), increased time to rescue analgesia (171.8 min; 95% CI, 112.34-231.26), and decreased pain scores (scale of 0 to 10) at 4 hours (MD, −0.36; 95% CI, −0.65 to −0.07) and 8 hours (MD, −0.17; 95% CI, −0.29 to −0.04) after surgery. Frequency of adverse events was similar between the 2 groups (odds ratio, 1; 95% CI, 0.61-1.63). The estimates for pain scores were prone to sensitivity analysis. The estimates for postoperative opiate use, time to rescue analgesia, and pain scores at 8 hours had significant heterogeneity. Conclusions: The addition of Dex to LAs in the TAP block for analgesia after abdominal surgeries decreased 24-hour opiate use and increased the overall time to rescue analgesia including certain subgroups without increasing adverse events. Its effect on postoperative pain scores was not as definitive.
