Immediate compared with on-demand maternal full feeding after planned caesarean delivery: a randomised trial

Effect of early oral carbohydrate intake after elective Cesarean delivery on maternal body temperature and satisfaction: a randomized controlled trial

PURPOSE

Although the Enhanced Recovery After Cesarean Delivery (ERAC) consensus statement provides recommendations for early postoperative drinking and eating, evidence from high-quality clinical research directly addressing parturients is sparse. Our objective was to assess if early oral carbohydrate intake after elective Cesarean delivery improves maternal recovery.

METHODS

In this randomized controlled trial, we enrolled parturients undergoing elective Cesarean delivery under spinal anesthesia with tympanic membrane temperatures ≤ 36.5 °C immediately upon arrival at the postanesthesia care unit. Parturients were randomized to either 100 mL of oral complex carbohydrate intake (group CC) or 10 mL of water (group C). The primary outcome was maternal tympanic membrane temperature. Other outcomes included maternal thermal comfort score, degree of shivering, satisfaction, degree of thirst and hunger, and gastric emptying assessed by ultrasonography.

RESULTS

We included 90 participants in the final analysis. The mean (standard deviation [SD]) maternal body temperature at 120 min after ingestion was 36.7 (0.3) °C in group CC and 36.6 (0.3) °C in group C (difference in means, 0.14 °C; 95% confidence interval, 0.02 to 0.26; P = 0.02). Furthermore, using repeated measure models, the linear trends of temperature changes over time between groups CC and C were significantly different (P = 0.04). The thermal comfort scores at 120 min after ingestion were higher in group CC than in group C (P = 0.02), and the linear trends of shivering score changes over time between groups CC and C also were different (P = 0.003). The mean (SD) visual analogue scale scores for maternal satisfaction were 84 (13) mm in group CC and 47 (20) mm in group C (P < 0.001). Nevertheless, at 90 and 120 min after ingestion, there were no differences between the two groups in the number of participants with a gastric antrum cross-sectional area > 10.3 cm2.

CONCLUSIONS

Early oral carbohydrate intake after Cesarean delivery helped to restore maternal body temperature postoperatively and improve maternal satisfaction. Nevertheless, the clinical importance of these finding is unclear, given that most of the differences were small. In addition, there was no delay in maternal gastric emptying after consumption of a complex carbohydrate beverage in the early post-Cesarean period.

Immediate vs on-demand maternal oral full feeding after unplanned cesarean section during labor: a randomized controlled trial

BACKGROUND

The adoption of Enhanced Recovery After Cesarean is increasing, but evidence supporting individual interventions having a specific benefit to Enhanced Recovery After Cesarean is lacking. A key element in Enhanced Recovery After Cesarean is early oral intake. Maternal complications are more frequent in unplanned cesarean delivery. In planned cesarean delivery, immediate full feeding enhances recovery, but the effect of unplanned cesarean delivery during labor is not known.

OBJECTIVE

This study aimed to evaluate immediate oral full feeding vs on-demand oral full feeding after unplanned cesarean delivery in labor on vomiting and maternal satisfaction.

STUDY DESIGN

A randomized controlled trial was conducted in a university hospital. The first participant was enrolled on October 20, 2021, the last participant was enrolled on January 14, 2023, and follow-up was completed on January 16, 2023. Women were assessed for full eligibility on arrival at the postnatal ward after their unplanned cesarean delivery. The primary outcomes were vomiting in the first 24 hours (noninferiority hypothesis and 5% noninferiority margin) and maternal satisfaction with their feeding regimen (superiority hypothesis). The secondary outcomes were time to first feed; food and beverage quantum consumed at first feed; nausea, vomiting, and bloating at 30 minutes after first feed, at 8, 16, and 24 hours after the operation, and at hospital discharge; parenteral antiemetic and opiate analgesia use; first breastfeeding and satisfactory breastfeeding, bowel sound, and flatus; second meal; cessation of intravenous fluid; removal of a urinary catheter; urination; ambulation; vomiting during the rest of hospital stay; and serious maternal complications. Data were analyzed using the t test, Mann-Whitney U test, chi-square test, Fisher exact test, and repeated measures analysis of variance as appropriate.

RESULTS

Overall, 501 participants were randomized into immediate or on-demand oral full feeding (sandwich and beverage). Vomiting in the first 24 hours were reported by 5 of 248 participants (2.0%) in the immediate feeding group and 3 of 249 participants (1.2%) in the on-demand feeding group (relative risk, 1.7; 95% confidence interval, 0.4-6.9 [0.48%-8.28%]; P=.50), and the maternal satisfaction scores from 0 to 10 were 8 (6-9) for the immediate feeding group and 8 (6-9) for the on-demand feeding groups (P=.97). The times from cesarean delivery to the first meal were 1.9 hours (1.4-2.7) vs 4.3 hours (2.8-5.6) (P<.001), first bowel sound 2.7 hours (1.5-7.5) vs 3.5 hours (1.8-8.7) (P=.02), and second meal 7.8 hours (6.0-9.6) vs 9.7 hours (7.2-13.0) (P<.001). These intervals were shorter with immediate feeding. The participants were more likely to agree to recommend immediate feeding to a friend (228 [91.9%] in the immediate feeding group vs 210 [84.3%] in the on-demand feeding group; relative risk, 1.09; 95% confidence interval, 1.02-1.16; P=.009). However, at first feed for food, ate "nothing at all" rates were 10.4% (26/250) in the immediate group and 3.2% (8/247) in the on-demand group, and "eaten all" rates were 37.5% (93/249) in the immediate group and 42.8% (106/250) in the on-demand group (P=.02). Other secondary outcomes were not different.

CONCLUSION

Compared with on-demand oral full feeding, immediate oral full feeding after unplanned cesarean delivery in labor did not increase the maternal satisfaction score and was not noninferior on postoperation vomiting. On-demand feeding with its emphasis on patient autonomy could be preferred, but the earliest full feeding should be encouraged and provided.

[Effects of Early Oral Feeding versus Delayed Oral Feeding on Bowel Function, Gastrointestinal Complications and Surgical Recovery after Cesarean Section under Regional Anesthesia: Systematic Review and Meta-Analysis]

PURPOSE

This study aimed to assess combined effects of early oral feeding after Cesarean section (C/S) under regional anesthesia on bowel function, gastrointestinal complications and surgical recovery.

METHODS

A systematic literature search was conducted using KISS, RISS, PubMed, CINAHL, EMBASE, CENTRAL and Google Scholar to identify randomized clinical trials comparing early oral feeding (EOF) with delayed oral feeding (DOF) after C/S. Outcome variables were bowel function and gastrointestinal complications and surgical recovery. Effect size was calculated using weighted mean differences (WMDs) and relative risks (RRs), with 95% confidence intervals (CIs).

RESULTS

Seven studies involving 1,911 patients from 568 studies, 7 studies were included in meta-analysis. EOF was significantly associated with shorter time to recover bowel movement compared with DOF (WMD, -2.50; CI, -3.50~-1.50). EOF was not associated with nausea (RR, 1.15; CI, 0.87~1.53) and vomiting (RR, 0.96; CI, 0.65~1.42), but lower incidence of abdominal distension (RR, 0.70; CI, 0.50~0.98). EOF was significantly associated with shorter time to discontinuation of intravenous fluids (WMD, -8.88; 95% CI, -16.65~-1.11) and removal of urinary catheter (WMD, -15.23; CI, -25.62~-4.85).

CONCLUSION

This meta-analysis provides evidence that EOF after C/S under regional anesthesia not only accelerates return of bowel function and surgical recovery but also reduces gastrointestinal complications. These results suggest that EOF should be offered to women who have undergone C/S to improve the recovery experience and reduce overall medical costs.

Comparison of early and on-demand maternal feeding after Caesarean delivery: a prospective randomised trial

INTRODUCTION

This study aimed to compare early and on-demand maternal feeding after Caesarean delivery in terms of gastrointestinal complaints and patient satisfaction.

METHODS

A total of 262 women with uncomplicated singleton term pregnancies who underwent a Caesarean section under regional anaesthesia were randomised to a soft food diet served at Postoperative Hour 2 (early feeding group) or eating whenever they wanted to upon return to the ward (on-demand group). Patient satisfaction scores at the time of discharge and gastrointestinal complaints were compared.

RESULTS

The fed-early group comprised 133 (50.8%) women and the on-demand group comprised 129 (49.2%) women. Major characteristics and surgical procedures were comparable between the two groups. No significant between-group differences in demographic criteria or surgical procedures were evident (p > 0.05). The mean time to the first feeding was 120.00 ± 00.00 minutes for the early feeding group as compared to 236.59 ± 107.74 minutes for the on-demand feeding group (p = 0.001). Satisfaction levels did not differ significantly between the two groups (p = 0.366). Duration to first breastfeeding, analgesia on the ward, passage of flatus, defecation, mobilisation and urination after catheter removal did not differ significantly between the two groups (p > 0.05).

CONCLUSION

Early initiation of solid food in low-risk women after Caesarean delivery under regional anaesthesia was associated with high satisfaction and did not increase gastrointestinal complaints. We suggest having flexibility in terms of postoperative feeding time. This may shorten hospitalisation time and reduce hospitalisation costs.

Twelve-hour fasting compared with expedited oral intake in the initial inpatient management of hyperemesis gravidarum: a randomised trial

OBJECTIVE

To evaluate fasting for 12 hours compared with expedited oral feeding in hospitalised women with hyperemesis gravidarum (HG).

DESIGN

Randomised trial.

SETTING

University Hospital, Malaysia: April 2016-April 2017.

POPULATION

One hundred and sixty women hospitalised for HG.

METHOD

Women were randomised upon admission to fasting for 12 hours or expedited oral feeding. Standard HG care was instituted.

MAIN OUTCOME MEASURE

Primary outcome was satisfaction score with overall treatment at 24 hours (0-10 Visual Numerical Rating Scale VNRS), vomiting episodes within 24 hours and nausea VNRS score at enrolment, and at 8, 16 and 24 hours.

RESULTS

Satisfaction score, median (interquartile range) 8 (5-9) versus 8 (7-9) (P = 0.08) and 24-hour vomiting episodes were 1 (0-4) versus 1 (0-5) (P = 0.24) for 12-hour fasting versus expedited feeding, respectively. Repeated measures analysis of variance of nausea scores over 24 hours showed no difference (P = 0.11) between trial arms. Participants randomised to 12-hour fasting compared with expedited feeding were less likely to prefer their feeding regimen in future hospitalisation (41% versus 65%, P = 0.001), to recommend to a friend (65% versus 84%, P = 0.01; RR 0.8, 95% CI 0.6-0.9) and to adhere to protocol (85% versus 95%, P = 0.04; RR 0.9, 95% CI 0.8-1.0). Symptoms profile, ketonuria status at 24 hours and length of hospital stay were not different.

CONCLUSION

Advisory of 12-hour fasting compared with immediate oral feeding resulted in a non-significant difference in satisfaction score but adherence to protocol and fidelity to and recommendation of immediate oral feeding to a friend were lower. The 24-hour nausea scores and vomiting episodes were similar.

TWEETABLE ABSTRACT

Women hospitalised for hyperemesis gravidarum could feed as soon, as much and as often as can be tolerated compared with initial fasting.
