BACKGROUND AND OBJECTIVES: We investigated whether the injection of 10 mL of normal saline into the subarachnoid space following accidental dural puncture reduced the incidence of postdural puncture headache (PDPH) and the need for epidural blood patch (EBP). METHODS: Twenty-eight patients who experienced accidental dural puncture with an epidural needle had 10 mL of normal saline injected into the subarachnoid space. In 22 patients, the injection was performed immediately through the epidural needle. In 6 patients who had intrathecal catheters placed through the epidural needle, the saline was injected through the catheter before removal. All other patients who experienced wet taps during the same period that the study was in progress but did not receive the saline injection served as a control group, 26 in number. Patients with severe or persistent PDPHs were treated with EBP. RESULTS: Of those patients who received intrathecal normal saline immediately through the epidural needle, 32% developed a headache compared with 62% of controls. Of these, 1 patient who received saline required EBP compared with nine in the control group (P =.004). Of those patients who had intrathecal catheters placed, there were no headaches in the saline group of 6 compared with 3 in the control group of 5, 1 of whom was treated with EBP (P >.05). CONCLUSIONS: The immediate injection of 10 mL intrathecal normal saline after a wet tap significantly reduced the incidence of PDPH and the need for EBP. When an intrathecal catheter had been placed following a wet tap, injection of 10 mL of normal saline before its removal effectively prevented PDPH.  相似文献

BACKGROUND: Postdural puncture headache (PDPH) occurs in up to 80% of parturients who experience inadvertent dural puncture during epidural catheter placement. The authors performed a randomized double blind study to assess the effect of prophylactic epidural blood patch on the incidence of PDPH and the need for therapeutic epidural blood patch. METHODS: Sixty-four parturients who incurred inadvertent dural puncture were randomized to receive a prophylactic epidural blood patch with 20 ml autologous blood (prophylactic epidural blood patch group) or a sham patch (sham group). Subjects were evaluated daily for development of PDPH for a minimum of 5 days after dural puncture. Those who developed a PDPH were followed daily for a minimum of 3 days after resolution of the headache. Subjects with moderate headaches who reported difficulties performing childcare activities and all those with severe headaches were advised to receive a therapeutic epidural blood patch. RESULTS: Eighteen of 32 subjects in each group (56%) developed PDPH. Therapeutic blood patch was recommended in similar numbers of patients in each group. The groups had similar onset time of PDPH, median peak pain scores, and number of days spent unable to perform childcare activities as a result of postural headache. The median duration of PDPH, however, was shorter in the prophylactic epidural blood patch group. CONCLUSIONS: A decrease in the incidence of PDPH or the need for criteria-directed therapeutic epidural patch was not detected when a prophylactic epidural blood patch was administered to parturients after inadvertent dural puncture. However, prophylactic epidural blood patch did shorten the duration of PDPH symptoms.  相似文献

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.  相似文献

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.  相似文献

To examine the effects of prolonged (> 24 h) intrathecal catheterization with the use of postoperative analgesia on the incidence of post–dural puncture headache (PDPH), charts of 45 obstetric patients who had accidental dural puncture following attempts at epidural block were reviewed retrospectively. Three groups were identified: Group I (n = 15) patients had a dural puncture on the first attempt at epidural block, but successful epidural block on a repeated attempt; Group II (n=17) patients had a dural puncture with immediate conversion to continuous spinal anaesthesia with catheterization lasting only for the duration of caesarean delivery; Group III (n= 13) patients had an immediate conversion to spinal anaesthesia and received post–caesarean section continuous intrathecal patient–controlled analgesia consisting of fentanyl 5 (ig'ml-1 with bupivacaine 0.25 mg·ml-1 and epinephrine 2 μg·ml-1 with catheterization lasting >24 h. No parturient in group III developed a PDPH. This was substantially lower ( P < 0.009) than the 33% incidence for group I and the 47% incidence for group II. The incidence of a PDPH did not differ between group I and II. Similarly, there was no difference between group I and II with regard to requests for a blood patch. Patients receiving continuous intrathecal analgesia had excellent pain relief, could easily ambulate and none complained of pruritus, nausea, vomiting, sensory loss or weakness. In conclusion, indwelling spinal catheterization > 24 h with continuous intrathecal analgesia following accidental dural puncture in parturients may for some patients be a suitable method for providing PDPH prophylaxis and postoperative analgesia.  相似文献

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%).  相似文献

Post-dural puncture headache (PDPH) is one of the most common and debilitating complications of neuraxial blockade in the parturient. The obstetric population is at particular risk with up to 80% of women developing symptoms after inadvertent dural puncture during epidural insertion. PDPH typically develops 24–48 hours post-puncture and is classically described as an occipito-frontal headache with postural features. Diagnosis and assessment should include consideration of other potential causes of post-partum headache. At the time of inadvertent dural puncture (IDP) one may insert an intrathecal catheter, re-site the epidural or use alternative analgesia. Initial treatment of a PDPH includes bed rest, adequate hydration and simple analgesics. Epidural blood patch (EBP) remains the gold standard treatment of PDPH.  相似文献

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.  相似文献

BackgroundInserting an intrathecal catheter after accidental dural puncture in parturients to prevent postdural puncture headache is becoming increasingly popular. We aimed to identify relevant published articles investigating this intervention and subject data to a meta-analysis.MethodsA systematic literature search was performed, paralleled by a hand search of abstract publications. Studies that reported the dichotomous outcome parameters postdural puncture headache or need for an epidural blood patch were considered eligible. Risk ratios with 95% confidence intervals were calculated.ResultsWe identified nine reports investigating placement of intrathecal catheters after accidental dural puncture. The risk ratio for an epidural blood patch after intrathecal catheter insertion was 0.64 (95% CI 0.49–0.84, P = 0.001). The risk ratio for postdural puncture headache was 0.82 (95% CI 0.67–1.01, P = 0.06).DiscussionInserting an intrathecal catheter significantly reduced the risk for an epidural blood patch; the incidence of postdural puncture headache was reduced but not significantly. Accidental dural puncture is a rare complication and therefore trials on intervention need to include a large number of patients which is time-consuming and costly. Intrathecal catheterisation is a promising approach for the prevention of postdural puncture headache and should be evaluated further. This intervention has additional benefits including a reduced risk of repeat dural puncture, rapid onset of action and use for anaesthesia.  相似文献

Purpose

We investigated whether inserting an intrathecal catheter and leaving it in place for 24 h after an unintentional dural puncture in orthopedic patients reduced the incidence of post-dural puncture headache (PDPH).

Methods

The study consisted of 427 patients in whom a total of 21 unintentional dural punctures had occurred during orthopedic surgery performed between 2002 and 2006. Seven patients (phase I; evaluated retrospectively) each underwent placement of an epidural catheter at another level after dural puncture during the period January 2002 to February 2004. Fourteen patients (phase II; evaluated prospectively) received an epidural catheter through the dural tear after an unintentional dural puncture during the period February 2004–March 2006

Results

In phase I, 5 of the 7 patients experienced PDPH, and one required an epidural blood patch. In phase II, only one of the 14 patients complained of PDPH, which resolved after 48 h of medical therapy. No patient experienced paresthesia, neurologic or hemorrhagic complication, or infection.

Conclusion

Inserting an epidural catheter through the dural tear following an unintentional dural puncture and leaving it in place for 24 h significantly reduces the incidence of PDPH.  相似文献

Purpose

To describe the anaesthetic management and report the incidence of PDPH in three parturients who had experienced accidental durai puncture during labour and the subsequent deliberate intrathecal insertion of an epidural catheter.

Clinical features

Inadvertent durai puncture with a 16-gauge Tuohy needle occurred during the first stage of labour at 3–4 cm cervical dilatation in all three women. The 20-gauge epidural catheter was immediately inserted into the subarachnoid space after accidental durai penetration. Intermittent intrathecal injections of lidocaine or bupivacaine with fentanyl were administered to provide analgesia during labour and delivery. Two of the women had spontaneous vaginal deliveries, whereas Caesarean section was performed in one case due to acute fetal distress during the second stage of labour. The intrathecal catheter was left in-situ for 13–19 hr after delivery and the women were questioned daily for symptoms of PDPH. None of the three women developed PDPH after dural puncture and intrathecal catheterisation with the epidural catheter.

Conclusion

Immediate intrathecal insertion of the epidural catheter after accidental durai puncture during labour proved to be an effective prophylactic technique to prevent PDPH in these three parturients.  相似文献

PURPOSE: To determine the association between bearing down, postdural puncture headache (PDPH) and epidural blood patch (EBP) following single 17 gauge unintentional dural puncture (UDP) in parturients. METHODS: The charts of 60 parturients identified with UDP in our institutional database during epidural placement were independently reviewed. Patients were divided into categories based on the anesthetic record: well-documented single punctures; well-documented multiple punctures; catheter-related puncture; unclear category (not clear if more than one puncture occurred or if dural puncture had occurred at all) and no evidence of dural puncture. Patients with single 17 gauge punctures were divided into those who had pushed (Group 1) and those who had not (Group 2). Group 2 patients had undergone Cesarean section before reaching second stage labour. The incidence of PDPH, EBP, and cumulative duration to delivery after UDP were compared between groups. RESULTS: Thirty-three patients with well-documented single punctures were identified: 23 had engaged in active pushing as part of second stage labour (Group 1); 10 had not (Group 2). Seventy-four percent of Group1I developed PDPH compared with 10% in Group 2 (P < 0.002). Fifty-seven percent of Group 1 received an EBP compared with 0% in Group 2 (P < 0.002). Increasing the duration of pushing was associated with an increasing incidence of PDPH; the majority of women who pushed > 30 min developed headache. CONCLUSIONS: An increased incidence of PDPH and EBP after UDP occurs in women bearing down in 2nd stage labour when compared with those who never pushed. There was also an association between the cumulative duration of bearing down and the incidence of PDPH.  相似文献

Postdural puncture headache (PDPH), a complication of regional anesthesia, is not infrequently seen in parturients because of their inherent risk from young age and female gender. With spinal anesthesia, the risk of PDPH is mainly dependent on the size and type of needle and can be reduced with the use of small-gauge, pencilpoint spinal needles. For unintentional dural puncture with epidural needles, a prophylactic epidural blood patch can reduce the risk of PDPH. Other potentially efficacious maneuvers include insertion of an intrathecal catheter and avoidance of second- stage pushing. Treatment of PDPH includes the use of caffeine or an epidural blood patch. Other pharmacologic interventions (eg, theophylline, sumatriptan, adrenocorticotropic hormone) and epidural administration of saline or dextran 40 await further investigation. The evidence for these interventions is discussed in this review. Copyright © 2001 by W.B. Saunders Company  相似文献

Post-dural puncture headache (PDPH) is a common and debilitating complication of central neuraxial blockade in the parturient. The obstetric population is at particular risk with up to 80% of women developing symptoms after accidental dural puncture (ADP) during labour epidural insertion. PDPH typically develops 24–48 hours post puncture and is classically described as an occipito-frontal headache with postural features. Diagnosis and assessment should include consideration of other potential causes of post-partum headache. Initial treatment of PDPH includes adequate hydration and analgesics. Epidural blood patch (EBP) remains the gold standard treatment. It is more successful if performed over 24–48 hours after the development of symptoms. Complete and permanent relief of symptoms following a single EBP occurs in up to one third of cases where headache follows ADP with an epidural needle. Complete or partial relief may be seen in 50–80% overall. Higher success rates are achieved following a second EBP. There is now UK national guidance on the treatment of post dural puncture headache published by the Obstetric Anaesthetists Association (OAA).  相似文献

Accidental dural puncture (ADP) is a common complication of epidural catheter insertion, and may lead to post-dural puncture headache (PDPH), especially in obstetric patients. Epidural blood patch (BP) is the most effective treatment of PDPH. Prophylactic BP has shown its efficacy to prevent PDPH; nevertheless, this method may be insufficient. We report an ADP case before induction of labor in a 28-year-old parturient. To avoid PDPH, an intrathecal catheter was immediately inserted after ADP and an epidural catheter was also inserted at the interspace above. Catheters were kept in place for more than 24 hours. A prophylactic BP was performed immediately after removal of the intrathecal catheter. The patient did not experience any headache. This combination of treatments (intrathecal catheter insertion + prophylactic BP) may be a good alternative approach to prevent PDPH, even if it has to be warranted by other clinical studies.  相似文献

PURPOSE: A prospective, randomized trial in labouring parturients was undertaken to assess whether the 18G Special Sprotte epidural needle is associated with a lower incidence of accidental dural puncture (ADP) in comparison with the 17G Tuohy needle. A secondary purpose was to determine if the incidence of postdural puncture headache (PDPH ) differed between groups when ADP occurred. METHODS: Following Institutional Review Board approval 1,077 parturients requesting epidural analgesia at three tertiary obstetrical units were randomized to epidural catheter insertion with a 17G Tuohy or 18G Special Sprotte needle. Patients were followed for seven days by a blinded assessor to determine the occurrence of PDPH using standardized criteria. If postural headache or neck ache presented, an ADP was diagnosed even if cerebrospinal fluid (CSF) was not observed at insertion. This subgroup was followed daily to assess headache characteristics and response to blood patch. RESULTS: Six Tuohy group patients, and two patients in the Sprotte group were excluded. One of the six excluded in the Tuohy group had an ADP. Twenty-eight ADPs occurred, nine unrecognized by CSF visualization (1.8% Tuohy, 3.4% Sprotte, P = 0.12). The incidence of unrecognized ADPs was higher in the Sprotte group (40% Sprotte vs 20% Tuohy, P < 0.05). If ADP occurred, the incidence of PDPH was lower in the Sprotte group (100% Tuohy vs 55% Sprotte, P = 0.025). The ease of use, and user satisfaction were higher in the Tuohy group (84 +/- 17.3% Tuohy vs 68.2 +/- 25.3% Sprotte, P < 0.001). CONCLUSION: The incidence of ADP was not reduced with the Special Sprotte epidural needle in comparison with the Tuohy needle, but PDPH after ADP occurred less frequently in the Sprotte group.  相似文献

Background: A major risk with epidural analgesia is accidental dural puncture (ADP), which may result in post‐dural puncture headache (PDPH). This survey was conducted to explore the incidence of ADP, the policy for management of PDPH and the educational practices in epidural analgesia during labour in the Nordic countries. Methods: A postal questionnaire was sent to the anaesthesiologist responsible for Obstetric anaesthesia service in all maternity units (n=153) with questions relating to the year 2008. Results: The overall response rate was 93%. About 32% (22–47%) of parturients received epidural analgesia for labour. There were databases for registering obstetric epidural complications in 13% of Danish, 24% of Norwegian and Swedish, 43% of Finnish and 100% of hospitals in Iceland. The estimated incidence of ADP was 1% (n≈900). Epidural blood patch (EBP) was performed in 86% (n≈780) of the parturients. The most common time interval from diagnosis to performing EBP was 24–48 h. The success rate for EBP was >75% in 67% (62–79%) of hospitals. The use of diagnostic CT/MRI before the first or the second EBP was exceptional. No major complication was reported. Teaching of epidurals was commonest (86%) in the non‐obstetric population and 53% hospitals desired a formal training programme in obstetric analgesia. Conclusion: We found the incidence of ADP to be approximately 1%. EBP was the commonest method used for its management, and the success rate was high in most hospitals. Formal training in epidural analgesia was absent in most countries and trainees first performed it in the non‐obstetric population.  相似文献
