A randomized study to evaluate post-dural puncture headache after cesarean section: Comparison with median and paramedian approaches

Ultrasound-guided caudal anaesthesia combined with epidural anaesthesia for caesarean section: a randomized controlled clinical trial

BACKGROUND

Although epidural anaesthesia and spinal anaesthesia are currently the general choices for patients undergoing caesarean section, these two neuraxial anaesthesia methods still have drawbacks. Caudal anaesthesia has been considered to be more appropriate for gynaecological surgery. The purpose of this study was to compare epidural anaesthesia combined with caudal anaesthesia, spinal anaesthesia and single-space epidural anaesthesia for caesarean section with respect to postoperative comfort and intraoperative anaesthesia quality.

METHODS

In this clinical trial, 150 patients undergoing elective caesarean section were recruited and randomized into three groups according to a ratio of 1:1:1to receive epidural anaesthesia only, spinal anaesthesia only or epidural anaesthesia combined with caudal anaesthesia. The primary outcome was postoperative comfort in the three groups. Secondary outcomes included intraoperative anaesthesia quality and the incidences of nausea, vomiting, postdural puncture headache, maternal bradycardia, or hypotension.

RESULTS

More patients were satisfied with the intraoperative anaesthesia quality in the EAC group than in the EA group (P = 0.001). The obstetrician was more significantly satisfied with the intraoperative anaesthesia quality in the SA and EAC groups than in the EA group (P = 0.004 and 0.020, respectively). The parturients felt more comfortable after surgery in the EA and EAC groups (P = 0.007). The incidence of maternal hypotension during caesarean section was higher in the SA group than in the EA and EAC groups (P = 0.001 and 0.019, respectively).

CONCLUSIONS

Epidural anaesthesia combined with caudal anaesthesia may be a better choice for elective caesarean section. Compared with epidural anaesthesia and spinal anaesthesia, it has a higher quality of postoperative comfort and intraoperative anaesthesia.

Paramedian versus midline approach of spinal anesthesia: a systematic review and meta-analysis with trial sequential analysis

PURPOSE

Midline approach of spinal anesthesia has been widely used for patients undergoing surgical procedures. However, it might not be effective for obstetric patients and elderly with degenerative spine changes. Primary objective was to examine the success rate at the first attempt between the paramedian and midline spinal anesthesia in adults undergoing surgery.

METHODS

Databases of MEDLINE, EMBASE, and CENTRAL were searched from their starting date until February 2023. Randomized clinical trials (RCTs) comparing the paramedian versus midline approach of spinal anesthesia were included. The primary outcome was the success rate at the first attempt of spinal anesthesia.

RESULTS

Our review included 36 RCTs (n = 5379). Compared to the midline approach, paramedian approach may increase success rate at the first attempt but the evidence is very uncertain (OR: 0.47, 95% CI 0.27-0.82, ρ = 0.007, level of evidence:very low). Our pooled data indicates that the paramedian approach likely reduced incidence of post-spinal headache (OR: 2.07, 95% CI 1.51-2.84, ρ < 0.00001, level of evidence:moderate). The evidence suggests that the paramedian approach may result in a reduction in the occurrence of paresthesia (OR: 1.61, 95% CI 1.06-2.45, ρ = 0.03, level of evidence:low).

CONCLUSIONS

Our meta-analysis of 36 RCTs showed that paramedian approach may result in little to no difference in success rate at the first attempt owing to its very low level of evidence. However, given the low level of evidence and studies with small sample sizes, these findings need to be interpreted with caveat.

Evidence-based clinical practice guidelines on postdural puncture headache: a consensus report from a multisociety international working group

INTRODUCTION

Postdural puncture headache (PDPH) can follow unintentional dural puncture during epidural techniques or intentional dural puncture during neuraxial procedures such as a lumbar puncture or spinal anesthesia. Evidence-based guidance on the prevention, diagnosis or management of this condition is, however, currently lacking. This multisociety guidance aims to fill this void and provide practitioners with comprehensive information and patient-centric recommendations to prevent, diagnose and manage patients with PDPH.

METHODS

Based on input from committee members and stakeholders, the committee cochairs developed 10 review questions deemed important for the prevention, diagnosis and management of PDPH. A literature search for each question was performed in MEDLINE (Ovid) on 2 March 2022. The results from each search were imported into separate Covidence projects for deduplication and screening, followed by data extraction. Additional relevant clinical trials, systematic reviews and research studies published through March 2022 were also considered for the development of guidelines and shared with contributors. Each group submitted a structured narrative review along with recommendations graded according to the US Preventative Services Task Force grading of evidence. The interim draft was shared electronically, with each collaborator requested to vote anonymously on each recommendation using two rounds of a modified Delphi approach.

RESULTS

Based on contemporary evidence and consensus, the multidisciplinary panel generated 50 recommendations to provide guidance regarding risk factors, prevention, diagnosis and management of PDPH, along with their strength and certainty of evidence. After two rounds of voting, we achieved a high level of consensus for all statements and recommendations. Several recommendations had moderate-to-low certainty of evidence.

CONCLUSIONS

These clinical practice guidelines for PDPH provide a framework to improve identification, evaluation and delivery of evidence-based care by physicians performing neuraxial procedures to improve the quality of care and align with patients' interests. Uncertainty remains regarding best practice for the majority of management approaches for PDPH due to the paucity of evidence. Additionally, opportunities for future research are identified.

The effect of postdural puncture headache on pre-existing and new-onset headaches after cesarean section: A retrospective study

Background

Obstetric patients are at higher risk of postdural puncture headache (PDPH) than other age- and sex-matched individuals. The debate over the long-term effects of PDPH continues. In this study, we aimed to assess the development of new-onset headaches or worsening of pre-existing chronic headaches in patients who underwent cesarean section under spinal anesthesia and developed PDPH.

Methods

Forty patients who developed PDPH (Group P) after cesarean section surgery (post-cesarean section–PCS), 80 patients who underwent cesarean section under spinal anesthesia (Group S), and 80 patients who underwent cesarean section under general anesthesia (Group G) were evaluated in the study. Chronic headache and other related symptoms that were present before pregnancy (pre-gestational–PG) and within 12 months after cesarean section were assessed.

Results

Eight of the 40 patients in Group P had a new-onset chronic headache after cesarean surgery, which was significantly higher than the rates in the other groups (p = 0.001). Of the patients whose pre-existing headache worsened during the PCS period, seven were in Group P, and four were in Group S (p = 0.020), while none was in Group G. According to the multiple logistic regression analysis, the risk of worsening headache increased by 1.51-fold for every 1 unit increase in the PG Numerical Rating Scale (NRS).

Conclusion

In conclusion, patients who develop PDPH appear to be at higher risk of developing new-onset headaches or worsening of pre-existing headaches compared with those who do not. We believe that keeping a headache diary for patients who will undergo dural puncture for whatever purpose, and also long-term follow-up of these patients for the risk of chronic headaches may increase awareness of this issue.

Telemedicine in Surgical Care in Low- and Middle-Income Countries: A Scoping Review

Background

Access to timely and quality surgical care is limited in low- and middle-income countries (LMICs). Telemedicine, defined as the remote provision of health care using information, communication and telecommunication platforms have the potential to address some of the barriers to surgical care. However, synthesis of evidence on telemedicine use in surgical care in LMICs is lacking.

Aim

To describe the current state of evidence on the use and distribution of telemedicine for surgical care in LMICs.

Methods

This was a scoping review of published and relevant grey literature on telemedicine use for surgical care in LMICs, following the PRISMA extension for scoping reviews guideline. PubMed-Medline, Web of Science, Scopus and African Journals Online databases were searched using a comprehensive search strategy from 1 January 2010 to 28 February 2021.

Results

A total of 178 articles from 53 (38.7%) LMICs across 11 surgical specialties were included. The number of published articles increased from 2 in 2010 to 44 in 2020. The highest number of studies was from the World Health Organization Western Pacific region (n = 73; 41.0%) and of these, most were from China (n = 69; 94.5%). The most common telemedicine platforms used were telephone call (n = 71, 39.9%), video chat (n = 42, 23.6%) and WhatsApp/WeChat (n = 31, 17.4%). Telemedicine was mostly used for post-operative follow-up (n = 71, 39.9%), patient education (n = 32, 18.0%), provider training (n = 28, 15.7%) and provider-provider consultation (n = 16, 9.0%). Less than a third (n = 51, 29.1%) of the studies used a randomised controlled trial design, and only 23 (12.9%) reported effects on clinical outcomes.

Conclusion

Telemedicine use for surgical care is emerging in LMICs, especially for post-operative visits. Basic platforms such as telephone calls and 2-way texting were successfully used for post-operative follow-up and education. In addition, file sharing and video chatting options were added when a physical assessment was required. Telephone calls and 2-way texting platforms should be leveraged to reduce loss to follow-up of surgical patients in LMICs and their use for pre-operative visits should be further explored. Despite these telemedicine potentials, there remains an uneven adoption across several LMICs. Also, up to two-thirds of the studies were of low-to-moderate quality with only a few focusing on clinical effectiveness. There is a need to further adopt, develop, and validate telemedicine use for surgical care in LMICs, particularly its impact on clinical outcomes.

Incidence and risk factors of “postdural puncture headache” in women undergoing cesarean delivery under spinal anesthesia with 26g quincke spinal needle, experience of medical college in rural settings in India 2019: A prospective cohort study design

Introduction:

Almost every cesarean delivery is done under spinal anesthesia because of ease of doing, rapid onset, avoids maternal and fetal risk of general anesthesia, promotes early recovery. Major complication especially in young women undergoing LSCS under spinal anesthesia is post dural puncture headache (PDPH) which is caused by cerebrospinal fluid leakage. There is wide variation in reported incidence of PDPH (0.3% to 40 %) after spinal anesthesia being affected by various procedure and non procedure related risk factors like age, gender, needle size and type, numbers of spinal attempts and previous history of PDPH.

Methods:

Prospective cohort study was conducted in 335 patients posted for caesarean section under spinal anesthesia from January 2019 to September 2019 in medical College situated in rural India. Spinal anesthesia was given by 26 G Quincke spinal needle. All patients were evaluated for incidence and severity of PDPH from post operative day 1 to day 5.

Result:

Incidence of PDPH was 11.4% in this study. Majority of patients (62.5%) were having mild pain. All patients reported PDPH with 72 hours.

Conclusion:

Body mass index (BMI), h/o PDPH, multiple attempts for successful spinal anesthesia did not have any significant association with PDPH in our study.

Prevalence and associated factors of post dural puncture headache among parturients who underwent cesarean section with spinal anesthesia: A systemic review and meta-analysis, 2021

Introduction

PDPH is a headache that develops after dural puncture which worsens in an upright position, and improves with lying down. It could affect maternal satisfaction and health care quality. The prevalence and factors of PDPH vary based on different literature and there is no previous meta-analysis done.

Methods

This study was done by searching studies from databases PubMed/MEDLINE, Google scholar, and google. Data were extracted by three reviewers independently by using Microsoft Excel and then exported to STATA™ 16 version statistical software for analysis. Heterogeneity assessed using the I² statistic. With a random model meta-analysis, the pooled prevalence of post-dural puncture headache and its associated factors (POR) with a 95% confidence interval was estimated.

Result

Eight studies with a total of 175, 652 study participants were included to estimate the pooled prevalence of PDPH following cesarean section under spinal anesthesia. The pooled prevalence of PDPH in this meta-analysis was found to be 23.47% with 95% CI (10.53, 36.42). Having normal BMI, multiple attempts of spinal injection and spinal injection with a needle size of less than or equal to 22 gauge were positively associated with the PDPH with AOR and 95% CI of 1.22 (1.09, 1.35), 3.50 (1.55, 5.44) and 7.36 (4.93, 9.80) respectively.

Conclusion

The pooled prevalence of PDPH among parturients who gave birth with the cesarean section under spinal anesthesia is estimated to be 23.47%. Having normal BMI, multiple attempts of spinal injection, and spinal injection with a needle size of less than or equal to 22 gauge were positively associated with the PDPH.

•

PDPH is one of the complications of spinal anesthesia.

•

Pooled prevalence of PDPH was 23.47% with 95% CI (10.53, 36.42).

•

Normal BMI, multiple attempt and spinal needle ≤22 gauge were associated factors.

THE COMPLICATIONS OF SPINAL ANESTHESIA IN OBSTETRIC AND GYNECOLOGICAL SURGICAL PROCEDURES

Background: The proper use of spinal anesthesia in surgical procedures will minimize patient’s referral. The objectives of the study were to determine the immediate and late complications of spinal anesthesia in obstetric and gynecological surgical procedures in our population. Material and Methods: This cross-sectional study was conducted in the Department of Gynecology and Obstetrics, Moulvi Ameer Shah Memorial Hospital, Peshawar, Pakistan from January 2014 to December 2014. Sample size was 790, selected through consecutive sampling technique. All routine and emergency obstetrical and gynecological cases were included. The exclusion criteria were those having hypotension, shock, coagulopathy, prolonged surgeries, patient’s refusal and local spinal disease. The demographic variables were; number of attempts, failure of anesthesia, vomiting, hypotension, respiratory problems, pain, Puncture site pain, and post dural puncture headache. All variables being categorical were analyzed by frequency and percentages using SPSS Version 16.0. Results: Out of 790 obstetrics and gynecology patients undergoing spinal anesthesia, there were 752 (95.2%) patients anaesthetized on first attempt whereas 38 (4.8%) required >1 attempts. Spinal anesthesia failed in 17 (2.1%) cases, partially failed in 15(1.9%). Post-operative mild hypotension was observed in 25 (3.1%) patients and severe hypotension in 4 (0.5%) cases. Respiratory problems were noted among 12 (1.9%). Patient’s Post-operative pain was observed in 28 (3.5%) patients. Nausea and vomiting were noted in 68 patients (8.6%).Late complications include post-operative mild to moderate pain in 65 (8.2%), severe in 15 (1.9%). Puncture site pain was observed in 8 (1.0%) of patients. Severe post dural puncture headache was noted in 3 (.38%). Conclusion: Spinal anesthesia in obstetric and gynecological surgical patients is easy to administer, safer and effective.
