Decreased incidence of headache after unintentional dural puncture in patients with cesarean delivery administered with postoperative epidural analgesia

Purpose  To investigate how subsequent placement of a catheter into the epidural space after unintentional dural puncture for postoperative analgesia for 36–72 h affected the incidence of post-dural puncture headache (PDPH). Methods  The records of 52 parturients who had had accidental dural puncture in cesarean delivery were reviewed. The parturients were assigned to two groups. Twenty-eight parturients were assigned to the study group, in whom an epidural catheter was inserted and was used for anesthesia and postoperative analgesia. Twenty-four parturients were assigned to the control group, in whom spinal anesthesia (n = 20) or general anesthesia (n = 4) was applied. For postoperative analgesia in patients with incision pain above visual analog scale (VAS) 3, 3 mg morphine in 15 ml saline was administered through the epidural catheter in the study group, while intramuscular meperidine or tramadol was administered in the control group. Once PDPH was observed, conservative treatment was tried first. If the headache persisted despite conservative treatment, an epidural blood patch was applied through the catheter or a reinserted epidural needle. Results  The study group demonstrated significant reduction of the incidence of PDPH and reduction in the indication for an epidural blood patch compared to the control group (7.1% vs 58% [P = 0.000] and 3.6% vs 37.5% [P = 0.002], respectively). Conclusion  Subsequent catheter placement into the epidural space after unintentional dural puncture in cesarean delivery and leaving the catheter for postoperative analgesia for 36–72 h may reduce the incidence of PDPH.     

The effect of placement and management of intrathecal catheters following accidental dural puncture on the incidence of postdural puncture headache and severity: a retrospective real-world study

Accidental dural puncture during an attempt to establish labour epidural analgesia can result in postdural puncture headache and long-term debilitating conditions. Epidural blood patch, the gold standard treatment for this headache, is invasive and not always successful. Inserting an intrathecal catheter after accidental dural puncture may prevent postdural puncture headache. We evaluated the effect of intrathecal catheter insertion on the incidence of postdural puncture headache and the need for epidural blood patch and whether duration of intrathecal catheterisation or injection of intrathecal saline affected outcome. Our retrospective study was conducted at two tertiary, university-affiliated medical centres between 2017 and 2022 and included 92,651 epidurals and 550 cases of accidental dural puncture (0.59%); 219 parturients (39.8%) received an intrathecal catheter and 331 (60.2%) a resited epidural. Use of an intrathecal catheter versus resiting the epidural did not decrease the odds of postdural puncture headache, adjusted odds ratio (aOR) (95%CI) 0.91 (0.81–1.01), but was associated with a lower need for epidural blood patch (aOR (95%CI) 0.82 (0.73–0.91), p < 0.001). We found no benefit in leaving in the intrathecal catheter for 24 h postpartum (postdural puncture headache, aOR (95%CI) 1.01 (1.00–1.02), p = 0.015; epidural blood patch, aOR (95%CI) 1.00 (0.99–1.01), p = 0.40). We found an added benefit of injecting intrathecal saline as it decreased the incidence of postdural puncture headache (aOR (95%CI) 0.85 (0.73–0.99), p = 0.04) and the need for epidural blood patch (aOR (95%CI) 0.75 (0.64–0.87), p < 0.001). Our study confirms the benefits of intrathecal catheterisation and provides guidance on how to best manage an intrathecal catheter.     

Intrathecal catheter use after accidental dural puncture in obstetric patients: literature review and clinical management recommendations

If an accidental dural puncture occurs, one option is to insert a catheter and use it as an intrathecal catheter. This avoids the need for a further injection and can rapidly provide labour analgesia and anaesthesia for caesarean section. However, there are no recommendations for managing intrathecal catheters and, therefore, significant variation in clinical practice exists. Mismanagement of the intrathecal catheter can lead to increased motor block, high spinal anaesthesia, drug error, hypotension and fetal bradycardia. Care must be taken with an intrathecal catheter to adhere to strict aseptic technique, meticulous labelling, cautious administration of medications and good communication with the patient and other staff. Every institution considering the use of intrathecal catheters should establish a protocol. For labour analgesia, we recommend the use of dilute local anaesthetic agents and opioids. For caesarean section anaesthesia, gradual titration to the level of the fourth thoracic dermatome, with full monitoring, in a facility equipped to manage complications, should be performed using local anaesthetics combined with lipophilic opioids and morphine or diamorphine. Although evidence of the presence and duration of intrathecal catheters on the development of post-dural puncture headache and need for epidural blood patch is limited, we suggest considering leaving the intrathecal catheter in for 24 hours to reduce the chance of developing a post-dural puncture headache while maintaining precautions to avoid drug error and cerebrospinal fluid leakage. Injection of sterile normal saline into the intrathecal catheter may reduce post-dural puncture headache. The level of evidence for these recommendations was low.     

Persistent headache and low back pain after accidental dural puncture in the obstetric population: a prospective,observational, multicentre cohort study

Accidental dural puncture following epidural insertion can cause a post-dural headache that is defined by the International Headache Society as self-limiting. We aimed to confirm if accidental dural puncture could be associated with persistent headache and back pain when compared with matched control parturients. We performed a prospective multicentre cohort study evaluating the incidence of persistent headache following accidental dural puncture at nine UK obstetric units. Parturients who sustained an accidental dural puncture were matched with controls who had undergone an uneventful epidural insertion. Participants were followed-up at six-monthly intervals for 18 months. Primary outcome was the incidence of persistent headache at 18 months. Ninety parturients who had an accidental dural puncture were matched with 180 controls. The complete dataset for primary analysis was available for 256 (95%) participants. Incidence of persistent headache at 18 months was 58.4% (52/89) in the accidental puncture group and 17.4% (29/167) in the control group, odds ratio (95%CI) 18.4 (6.0–56.7), p < 0.001, after adjustment for past history of headache, Hospital Anxiety and Depression Scale (depression) and Hospital Anxiety and Depression Scale (anxiety) scores. Incidence of low back pain at 18 months was 48.3% (43/89) in the accidental puncture group and 17.4% (29/167) in the control group, odds ratio (95%CI) 4.14 (2.11–8.13), with adjustment. We have demonstrated that accidental dural puncture is associated with long-term morbidity including persistent headache in parturients. This challenges the current definition of post-dural puncture headache as a self-limiting condition and raises possible clinical, financial and medicolegal consequences.     

Decrease in the incidence of post-dural puncture headache: maintaining CSF volume

The incidence of epidural needle-induced post-dural puncture headache (PDPH) in parturients following dural puncture with a large bore (18-gauge) needle has been reported to range 76-85%. We describe seven cases in which the performance of epidural anesthesia in parturients was complicated by an unintentional dural puncture with an 18-gauge epidural needle. In all seven cases, the unintentional dural puncture was followed by (i) injection of the CSF in the glass syringe back into the subarachnoid space through the epidural needle, (ii) insertion of a epidural catheter into the subarachnoid space (now referred to as an intrathecal catheter), (iii) injection of a small amount of preservative free saline (3-5 ml) into the subarachnoid space through the intrathecal catheter, (iv) administration of bolus and then continuous intrathecal labor analgesia through the intrathecal catheter and then (v) leaving the intrathecal catheter in-situ for a total of 12-20 h. PDPH occurred in only one of these cases (14%).     

Relief of postural post dural puncture headache by an epidural blood patch 12 months after dural puncture

A 20-year-old previously healthy male presented at the pain clinic with chronic headache of about one year duration. Clinical examination revealed no pathological manifestations. During the consultation the patient was drinking Coca-Cola. On direct questioning he told that drinking Coca-Cola gave partial relief from the headache, and that the headache started after he had received two spinal anaesthetics for treatment of a lower leg fracture. Postural post dural puncture headache was now suspected and an epidural blood patch performed. Despite an interval of nearly 12 months since the dural punctures, a single epidural blood patch completely relieved the headache. This case history demonstrates that an epidural blood patch should be tried if a chronic post dural puncture headache is suspected.     

Intrathecal catheterisation after observed accidental dural puncture in labouring women: update of a meta-analysis and a trial-sequential analysis

BackgroundOur meta-analysis from 2013 showed that inserting a catheter intrathecally after an observed accidental dural puncture can reduce the need for epidural blood patch in labouring women requesting epidural analgesia. We updated our conventional meta-analysis and added a trial-sequential analysis (TSA).MethodsA systematic literature search was conducted to identify studies that compared inserting the catheter intrathecally with an epidural catheter re-site or with no intervention. The extracted data were pooled and the risk ratio (RR) and 95% confidence interval (95%CI) for the incidence of post-dural puncture headache (PDPH) was calculated, using the random effects model. A contour-enhanced funnel plot was constructed. A TSA was performed and the cumulative Z score, monitoring and futility boundaries were constructed.ResultsOur search identified 13 studies, reporting on 1653 patients, with a low risk of bias. The RR for the incidence of PDPH was 0.82 (95%CI 0.71 to 0.95) and the RR for the need for epidural blood patch was 0.62 (95%CI 0.49 to 0.79); heterogeneity of both analyses was high. The TSA showed that the monitoring or futility boundaries were not crossed, indicating insufficient data to exclude a type I error of statistical analysis. Contour-enhanced funnel plots were symmetric, suggesting no publication bias.ConclusionsConventional meta-analyses showed for the first time that intrathecal catheterisation can reduce the incidence of PDPH. However, TSA did not corroborate this finding. Despite increasing use in clinical practice there is no firm evidence on which to base a definite conclusion.     

Successful treatment of dural puncture headache with epidural saline infusion after failure of epidural blood patch

A case is presented of a 30-year-old female with a 4-month history of post-lumbar puncture headache (PLPHA) resulting from an accidental dural puncture during an attempted epidural anesthetic for cesarean section. Epidural blood patches were attempted at 4 days and 3 months post-lumbar puncture, but were unsuccessful. At 4 months post-lumbar puncture, a 24-h epidural saline infusion relieved the PLPHA for 48 h, but the headache returned. Finally, a second epidural saline infusion was done, followed by an epidural blood patch, which permanently cured the PLPHA. Follow-up to 4 months showed no return of the PLPHA. The rationale for epidural blood and saline patches is discussed.     

The management of accidental dural puncture and postdural puncture headache: a North American survey

Study Objective

To evaluate the management of accidental dural puncture (ADP) and postdural puncture headache (PDPH) among obstetric anesthesiologists practicing in North America.

Design

Questionnaire survey of individual members of the Society for Obstetric Anesthesia and Perinatology (SOAP).

Setting

University hospital.

Measurements

In June 2008, a 4-part, 83-item electronic survey was distributed to all North American members of SOAP. It contained questions about respondent demographics, epidural catheter and intrathecal catheter management after ADP, PDPH management, epidural blood patch (EBP) management, and patient follow-up.

Main Results

Of the 843 United States and Canadian members of SOAP who were surveyed, 160 responses were collected. Respondents reported placing an epidural 75% of the time and an intrathecal catheter 25% of the time following ADP. Common prophylactic and conservative treatment strategies included hydration, caffeine, and opioids by mouth; 76% of respondents leave an intrathecal catheter in place for 24 hours to reduce the frequency of headache. Epidural blood patches are placed by 81% of practitioners less than 24 hours after headache onset.

Conclusions

Protocols for ADP management are rare. There is wide variation in catheter management after dural puncture, measures used to prevent and treat a resultant headache, and EBP management.     

The association between labour epidural case volume and the rate of accidental dural puncture

Accidental dural puncture is a recognised complication of labour epidural placement and can cause a debilitating headache. We examined the association between labour epidural case volume and accidental dural puncture rate in specialist anaesthetists and anaesthesia trainees. We performed a retrospective cohort study of labour epidural and combined spinal-epidural nerve blocks performed between 1 July 2013 and 31 December 2017 at Waitemata District Health Board, Auckland, New Zealand. The mean (SD) annual number of obstetric epidural and combined spinal-epidural procedures for high-case volume specialists was 44.2 (15.0), and for low-case volume specialists was 10.0 (6.8), after accounting for caesarean section combined spinal-epidural procedures. Analysis of 7976 labour epidural and combined spinal-epidural procedure records revealed a total of 92 accidental dural punctures (1.2%). The accidental dural puncture rate (95%CI) in high-case volume specialists was 0.6% (0.4–0.9%) and in low-case volume specialists 2.4% (1.4–3.9%), indicating probable skill decay. The odds of accidental dural puncture were 3.77 times higher for low- compared with high-case volume specialists (95%CI 1.72–8.28, p = 0.001). Amongst trainees, novices had a significantly higher accidental dural puncture complication rate (3.1%) compared with registrars (1.2%), OR (95%CI) 0.39 (0.18–0.84), p = 0.016, or fellows (1.1%), 0.35 (0.16–0.76), p = 0.008. Accidental dural puncture complication rates decreased once trainees progressed past the ‘novice’ training stage.     

Spinal anaesthesia with 29 gauge Quincke point needles and post dural puncture headache in 2,378 patients

Two thousand three hundred and seventy–eight spinal anaesthetics using a 29 G Quincke point needle were administered in a District Hospital between May 1983 and December 1991. The overall post dural puncture headache rate (PDPH) was 1.2% with a maximum of 2.5% in patients between age 30 and 39. PDPH was related to the experience of using 29 G needles (0.5% in consultants versus 2.0% in trainees, P<0.05).     

Management of persistent post-dural puncture headache after repeated epidural blood patch

We report a case of persistent post-dural puncture headache (PDPH) in a patient despite two epidural blood patches (EBPs). Successful resolution of headache was achieved with a third EBP performed under computed tomography (CT) guidance. A 38-year-old female had a total abdominal hysterectomy under combined spinal-epidural anesthesia with no complications. After surgery, she developed a postural headache consistent with PDPH. The first EBP was performed by injecting autologous blood through the epidural catheter that was in situ. The second EBP was performed under fluoroscopy. The patient continued to have a persistent headache. A computed tomography (CT) myelogram demonstrated cerebrospinal fluid (CSF) leak at L3-4 level. A "directed" CT-guided blood patch was then performed successfully with resolution of the headache.     

Sequential higher epidural catheter re-insertion after accidental dural puncture ameliorates the frequency and severity of post-dural puncture headache

ObjectivesThis cohort study aimed to evaluate the outcome of a hypothesis to use higher level for epidural catheter insertion and activation when an epidural tap was encountered at a lower level during epidural analgesia for labor pain.MethodsEpidural analgesia for labor pain was conducted using a mixture of 0.125% bupivacaine and fentanyl 5 μg/ml (10–15 ml) in 5-ml increments and maintained using continuous epidural infusion of 0.125% bupivacaine and fentanyl 2 μg/ml at rate of (5–15 ml/h), subsequently adjusted according to the patients needs. All cases had accidental dural puncture (ADP) were managed immediately with re-insertion of the needle at a higher level and completion of the procedure and maintained using continuous epidural infusion of 0.0625% bupivacaine and fentanyl 2 μg/ml at rate of (6–12 ml/h) for 24 h after delivery. Postpartum follow-up was conducted for 30 days to comment on the occurrence and severity of post-dural puncture headache (PDPH). All patients developed PDPH were followed daily until resolution of their headache.ResultsAbout 4800 parturient were enrolled in the study, ADP occurred in 24 patients with a frequency of 0.5%. All cases were immediately managed by re-insertion of the needle at a higher level and the procedure was successfully completed without new dural puncture, with 100% re-insertion success rate, and patients were maintained on continuous epidural infusion for 24 h. Throughout 30-day follow-up; only six of 24 patients developed PDPH with a success rate of re-insertion procedure as a prophylactic modality for PDPH after ADP of 75%. PDPH was relieved with bed rest, liberal fluids and paracetamol for 4 days in four patients, while the 5th patient continued to complain but the patient refused to undergo epidural blood patch (EBP) and headache started to subside and patient stopped to complain by the 10th day, and the last patient agreed to undergo EBP; and headache was relived immediately after 2 h.ConclusionIt could be concluded that re-insertion of epidural catheter at higher level of accidental dural puncture with epidural continuous infusion for 24 h could be considered as an efficient prophylactic modality to safe guard against PDPH with success rate of 75% and minimizes its severity if occurred.     

The incidence of post dural puncture headache in children

One hundred and five children with malignant disease attended for lumbar puncture which was performed under general anaesthesia. A questionnaire was answered over the next three days to determine the incidence of post dural puncture headache. Ninety-seven questionnaires were returned and the results show that no child aged under ten years developed a headache. Of the children aged 10–12 years, two out of seventeen developed a headache (11.8%). In children aged 13–18 years, five out of ten developed a headache (50%).     

Effect of neuraxial technique after inadvertent dural puncture on obstetric outcomes and anesthetic complications

BackgroundThe aim of this study was to evaluate labor and delivery outcomes in parturients with inadvertent dural puncture managed by either insertion of an intrathecal catheter or a resited epidural catheter.MethodsThis was a retrospective cohort review of 235 parturients who had an inadvertent dural puncture during epidural placement over a six-year period. The primary outcome was the proportion of women with a delayed second stage of labor. Secondary outcomes were the proportion of cesarean deliveries, the proportion of cases resulting in post-dural puncture headache, and the incidence of failed labor analgesia.ResultsBaseline characteristics such as age, body mass index and parity were similar between the two groups. Among the 236 cases of inadvertent dural puncture, 173 women (73%) had an intrathecal catheter placed while 63 women (27%) had the epidural catheter resited. Comparing intrathecal with epidural catheters, there was no observed difference in the proportion of cases of prolonged second stage of labor (13% vs. 16%, P=0.57) and the overall rate of cesarean deliveries (17% vs. 16%, P=0.78). However, we observed a lower rate of post-dural puncture headache in women who had cesarean delivery compared to vaginal delivery (53% vs. 74%, P=0.007). A greater proportion of failed labor analgesia was observed in the intrathecal catheter group (14% vs. 2%, P=0.005).ConclusionThe choice of neuraxial technique following inadvertent dural puncture does not appear to alter the course of labor and delivery. Cesarean delivery decreased the incidence of post-dural puncture headache by 35%. Intrathecal catheters were associated with a higher rate of failed analgesia.

Epidural blood patch for management of postdural puncture headache in adolescents

BACKGROUND: In some patients spinal puncture (SP) is followed by postdural puncture headache (PDPH). When the symptoms of PDPH are severe and are not relieved within a few days an epidural blood patch (EBP) might be performed. The aim of this survey was to review requests for EBPs and to evaluate the effectiveness of EBP in patients aged 13-18 years during a 6.5 year period ending in June 2001. METHODS: The Information System Patient Measures Database was interrogated to identify patients who were referred for EBP. After identification, the patients' medical records were reviewed in detail for the characteristics of PDPH and other symptoms, and for the effectiveness of the EBP. RESULTS: Forty-two EBPs were performed after 40 SPs on 37 patients (24 girls, 13 boys). Epidural blood patches were performed twice in five patients. The reasons for repeating the procedure were repeat SP with new PDPH in three patients and an unsatisfactory effect in two patients. Twenty-eight of the 40 spinal punctures (70%) had been performed for diagnostic use and 10 (25%) for spinal anesthesia. Two patients (5%) developed PDPH after inadvertent dural puncture with an epidural needle. In 37 cases the criteria for PDPH were fulfilled, and one patient had a cerebrospinal fluid fistula headache. Two-thirds of the girls had associated symptoms of headache compared with one-third of the boys. Epidural blood patch was performed 1-22 days after SP with 0.2 ml/kg (mean) of autologous blood injected into the epidural space. The success rate of the first injection was 37 out of 40 EBP (93%), and the second injection was effective in both patients with recurred PDPH. CONCLUSION: Epidural blood patch seems to be an effective and safe procedure in adolescents for treating severe and persistent PDPH.     

Management of postdural puncture headache with epidural blood patch in children

BACKGROUND: Until the last decade, it was believed that postdural puncture headache (PDPH) was an uncommon complaint in children, but recent studies indicate that young children may develop PDPH after spinal puncture. When the symptoms are severe and are not relieved within a few days with analgesics, forced hydration and bed rest, then epidural blood patch (EBP) might be performed. METHODS: In this retrospective survey, we analysed EBP performed in Kuopio University Hospital between the years 1995 and 2000. RESULTS: During the 6-year period, seven EBP were performed in children aged 12 years or younger. Four out of the seven children had undergone a diagnostic spinal puncture, two had spinal anaesthesia and one child had spinal puncture for treatment of postoperative hygroma. Five children had a typical PDPH, one child had a cerebrospinal fluid fistula headache and one child had a headache similar to his migraine. EBP was performed 2-19 days after spinal puncture with 0.3 ml.kg-1 (mean) of autologous blood injected into the epidural space. CONCLUSIONS: EBP gave some relief of symptoms in all children. No complications related to EBP were noticed.     

超声引导腹横肌平面阻滞对剖宫产术后镇痛的影响

目的探讨超声引导腹横肌平面(TAP)阻滞对剖宫产术产妇术后镇痛效果的影响。方法择期于腰-硬联合麻醉下行剖宫产术的产妇80例,ASAⅠ或Ⅱ级,随机均分为两组:腹横肌平面阻滞组(T组)和对照组(C组)。T组于术毕行超声引导双侧TAP阻滞,每侧注射0.5%罗哌卡因20ml,C组不阻滞;两组均行PCIA,于术后2、4、6、8、24h时行静息、运动时VAS评分、Ramsay镇静评分及BCS舒适度评分。记录术后24h内PCIA中舒芬太尼用量;记录产妇满意度及不良反应的发生情况;计算术后24h内PCIA有效按压次数与实际按压次数比(D1/D2)。结果与C组比较,术后2、4、6hT组静息及运动时VAS评分明显降低,BCS舒适度评分明显升高(P0.05)。T组术后24h内PCIA中舒芬太尼用量明显少于C组(P0.05),D1/D2及产妇满意度明显高于C组(P0.05)。两组均未发生恶心、呕吐、皮肤瘙痒、胸闷等不良反应。结论超声引导TAP阻滞减少了产妇在剖宫产术后阿片类镇痛药的使用量,增强了术后镇痛效果,提高了产妇的舒适度和满意度。
