Abstract
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.

Abstract
Post-dural puncture headache is one of the most undesirable complications of spinal anaesthesia. Previous pairwise meta-analyses have either compared groups of needles or ranked individual needles based on the pooled incidence of post-dural puncture headache. These analyses have suggested both the gauge and needle tip design as risk-factors, but failed to provide an unbiased comparison of individual needles. This network meta-analysis compared the odds of post-dural puncture headache with needles of varying gauge and tip design. We searched randomised controlled trials in medical databases. The primary outcome measure of the network meta-analysis was the incidence of post-dural puncture headache. Secondary outcomes were procedural failure, backache and non-specific headache. Overall, we compared 11 different needles in 61 randomised controlled trials including a total of 14,961 participants. The probability of post-dural puncture headache and procedural failure was lowest with 26-G atraumatic needles. The 29-G cutting needle was more likely than three atraumatic needles to have the lowest odds of post-dural puncture headache, although with increased risk of procedural failure. The probability rankings were: 26 atraumatic > 27 atraumatic > 29 cutting > 24 atraumatic > 22 atraumatic > 25 atraumatic > 23 cutting > 22 cutting > 25 cutting > 27 cutting = 26 cutting for post-dural puncture headache; and 26 atraumatic > 25 cutting > 22 cutting > 24 atraumatic > 22 atraumatic > 25 atraumatic > 26 cutting > 29 cutting > 27 atraumatic = 27 cutting for procedural success. Meta-regression by type of surgical population (obstetric/non-obstetric) and participant position (sitting/lateral) did not alter these rank orders. This analysis provides an unbiased comparison of individual needles that does not support the use of simple rules when selecting the optimal needle. The 26-G atraumatic needle is most likely to enable successful insertion while avoiding post-dural puncture headache but, where this is not available, our probability rankings can help clinicians select the best of available options.

Abstract
BACKGROUND Post-dural puncture headache (PDPH) is one of the most common complications of diagnostic and therapeutic lumbar punctures. PDPH is defined as any headache occurring after a lumbar puncture that worsens within 15 minutes of sitting or standing and is relieved within 15 minutes of the patient lying down. Researchers have suggested many types of interventions to help prevent PDPH. It has been suggested that aspects such as needle tip and gauge can be modified to decrease the incidence of PDPH. OBJECTIVES To assess the effects of needle tip design (traumatic versus atraumatic) and diameter (gauge) on the prevention of PDPH in participants who have undergone dural puncture for diagnostic or therapeutic causes. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL and LILACS, as well as trial registries via the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) search portal in September 2016. We adopted the MEDLINE strategy for searching the other databases. The search terms we used were a combination of thesaurus-based and free-text terms for both interventions (lumbar puncture in neurological, anaesthesia or myelography settings) and headache. SELECTION CRITERIA We included randomized controlled trials (RCTs) conducted in any clinical/research setting where dural puncture had been used in participants of all ages and both genders, which compared different tip designs or diameters for prevention of PDPH DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. MAIN RESULTS We included 70 studies in the review; 66 studies with 17,067 participants were included in the quantitative analysis. An additional 18 studies are awaiting classification and 12 are ongoing. Fifteen of the 18 studies awaiting classification mainly correspond to congress summaries published before 2010, in which the available information does not allow the complete evaluation of all their risks of bias and characteristics. Our main outcome was prevention of PDPH, but we also assessed the onset of severe PDPH, headache in general and adverse events. The quality of evidence was moderate for most of the outcomes mainly due to risk of bias issues. For the analysis, we undertook three main comparisons: 1) traumatic needles versus atraumatic needles; 2) larger gauge traumatic needles versus smaller gauge traumatic needles; and 3) larger gauge atraumatic needles versus smaller gauge atraumatic needles. For each main comparison, if data were available, we performed a subgroup analysis evaluating lumbar puncture indication, age and posture.For the first comparison, the use of traumatic needles showed a higher risk of onset of PDPH compared to atraumatic needles (36 studies, 9378 participants, risk ratio (RR) 2.14, 95% confidence interval (CI) 1.72 to 2.67, I2 = 9%).In the second comparison of traumatic needles, studies comparing various sizes of large and small gauges showed no significant difference in effects in terms of risk of PDPH, with the exception of one study comparing 26 and 27 gauge needles (one study, 658 participants, RR 6.47, 95% CI 2.55 to 16.43).In the third comparison of atraumatic needles, studies comparing various sizes of large and small gauges showed no significant difference in effects in terms of risk of PDPH.We observed no significant difference in the risk of paraesthesia, backache, severe PDPH and any headache between traumatic and atraumatic needles. Sensitivity analyses of PDPH results between traumatic and atraumatic needles omitting high risk of bias studies showed similar results regarding the benefit of atraumatic needles in the prevention of PDPH (three studies, RR 2.78, 95% CI 1.26 to 6.15; I2 = 51%). AUTHORS' CONCLUSIONS There is moderate-quality evidence that atraumatic needles reduce the risk of post-dural puncture headache (PDPH) without increasing adverse events such as paraesthesia or backache. The studies did not report very clearly on aspects related to randomization, such as random sequence generation and allocation concealment, making it difficult to interpret the risk of bias in the included studies. The moderate quality of the evidence for traumatic versus atraumatic needles suggests that further research is likely to have an important impact on our confidence in the estimate of effect.

Abstract
BACKGROUND Thoracic spinal anesthesia has been used for laparoscopic cholecystectomy and abdominal surgeries, but not in breast surgery. The present study compared this technique with general anesthesia in breast cancer surgeries. MATERIALS AND METHODS Forty patients were enrolled in this comparative study with inclusion criteria of ASA physical status I-III, primary breast cancer without known extension beyond the breast and axillary nodes, scheduled for unilateral mastectomy with axillary dissection. They were randomly divided into two groups. The thoracic spinal group (S) (n = 20) underwent segmental thoracic spinal anesthesia with bupivacaine and fentanyl at T5-T6 interspace, while the other group (n = 20) underwent general anesthesia (G). Intraoperative hemodynamic parameters, intraoperative complications, postoperative discharge time from post-anesthesia care unit (PACU), postoperative pain and analgesic consumption, postoperative adverse effects, and patient satisfaction with the anesthetic techniques were recorded. RESULTS Intraoperative hypertension (20%) was more frequent in group (G), while hypotension and bradycardia (15%) were more frequent in the segmental thoracic spinal (S) group. Postoperative nausea (30%) and vomiting (40%) during PACU stay were more frequent in the (G) group. Postoperative discharge time from PACU was shorter in the (S) group (124 ± 38 min) than in the (G) group (212 ± 46 min). The quality of postoperative analgesia and analgesic consumption was better in the (S) group. Patient satisfaction was similar in both groups. CONCLUSIONS Segmental thoracic spinal anesthesia has some advantages when compared with general anesthesia and can be considered as a sole anesthetic in breast cancer surgery with axillary lymph node clearance.

Abstract
AIMS In our group, after a study showing that spinal anesthesia is safe when compared with general anesthesia, spinal anesthesia has been the technique of choice for this procedure. This is a prospective study with all patients undergoing LC under spinal anesthesia in our department since 2007. SETTINGS AND DESIGN Prospective observational. MATERIALS AND METHODS From 2007 to 2011, 369 patients with symptoms of colelithiasis, laparoscopic cholecystectomy were operated under spinal anesthesia with pneumoperitoneum and low pressure CO2. We compared 15 mg of hyperbaric bupivacaine and lumbar puncture with 10 or 7.5 mg of hyperbaric bupivacaine thoracic puncture, all with 25 μg fentanyl until the sensory level reached T3. Intraoperative parameters, post-operative pain, complications, recovery, patient satisfaction, and cost were compared between both groups. STATISTICAL ANALYSIS USED Means were compared by ANOVA or Kruskal-Wallis test, the percentages of the Chi-square test or Fisher's exact test when appropriate. Time of motor and sensory block in spinal anesthesia group was compared by paired t test or Mann-Whitney test. Differences were considered significant when P ≤ 0.05, and for comparisons of mean pain visual scale, we employed the Bonferroni correction applied to be considered significant only with P ≤ 0.0125. RESULTS All procedures were completed under spinal anesthesia. The use of lidocaine 1% was successful in the prevention of shoulder pain in 329 (89%) patients. There were significant differences in time to reach T3, obtaining 15 mg > 10 mg = 7.5 mg. There is a positive correlation between the dose and the incidence of hypotension. The lowest doses gave a decrease of 52.2% in the incidence of hypotension. There was a positive correlation between the dose and duration of sensory and motor block. Sensory block was almost twice the motor block at all doses. With low doses, 60% of patients went from table to stretcher. Satisfaction occurred in 99% of patients. CONCLUSIONS Laparoscopic cholecystectomy can be performed successfully under spinal anesthesia with low-pressure pneumoperitoneum of CO2. The use of thoracic puncture and low doses of hyperbaric bupivacaine provided better hemodynamic stability, less hypotension, and shorter duration of sensory and motor blockade than lumbar spinal anesthesia with conventional doses.

Abstract
Background: The thoracic spinal anesthesia was first described in 1909 and recently revised for various surgical procedures. This is a prospective study aims to evaluate the parameters of the thoracic spinal anesthesia (latency, motor block and paresthesia), the incidence of cardiovascular changes and complications comparing low doses of isobaric and hyperbaric bupivacaine. Materials and Methods: A total of 200 orthopedic patients operated under spinal anesthesia were included in this study. Spinal anesthesia was between T9-T10, with a 27G cutting point or pencil tip in lateral or sitting. Spinal anesthesia was performed with 0.5% bupivacaine isobaric or hyperbaric. Patients remained in cephalad or head down position 10-20° for 10 minutes. We evaluated the demographics, analgesia, and degree of motor block, incidence of paresthesia, bradycardia, hypotension, anesthesia success and neurological complications. Results: All patients developed spinal and there was no failure. The solution did not affect the onset of the blockade. The duration of motor block was greater than the sensitive with isobaric. The duration of sensory block was greater than the motor block with hyperbaric solution. The incidence of paresthesia was 4%, with no difference between the needles. The incidence of hypotension was 12.5% with no difference between the solutions. There was no neurological damage in all patients. Conclusion: The beginning of the block is fast regardless of the solution used. By providing a sensory block of longer duration than the motor block hyperbaric bupivacaine is reflected in a better indication. Thoracic spinal anesthesia provides excellent anesthesia for lower limb orthopedic surgery

Abstract
BACKGROUND In adults, pencil point spinal needles are known to be less traumatic and hence to be superior compared with cutting point needles in respect of postpuncture complications. In children, only a few trials have evaluated the difference in the incidence of postdural puncture headache (PDPH) using spinal needles with different tip designs. The aim of this study was to evaluate the success rate and the incidence of PDPH and backache following spinal anesthesia (SA) with the two types of needles currently in use for children. METHODS This is a retrospective study of prospectively collected data. The success rate and postpuncture complications of 26G cutting point (Atraucan) spinal needle were compared with 27G pencil point (Pencan) spinal needle in 414 children aged 2-17 years undergoing surgery with SA. RESULTS Both needles had similar first-attempt success rates: 87% in the cutting point group and 91% in the pencil point group (P = 0.16). Pencil point needles caused less PDPH compared to cutting point needles; 0.4% vs 4.5%, respectively (P = 0.005). Both needles caused similar backache (P = 0.08). No severe neurologic symptom was reported for both needles. CONCLUSION The data suggest that 27G pencil point spinal needles lead to less PDPH compared to 26G cutting point spinal needles in children.

Abstract
Over the last 20 years, there has been a large increase in the proportion of caesarean sections (Brown and Russell, 1995) which are performed under regional rather than general anaesthesia. A bilateral sensory block from the T4 dermatome (nipple level) to the sacral nerve roots (perineum) is necessary.

Abstract
The aim of this study was to determine if patients with a previous history of postdural puncture headache (PDPH) might be prone to a new episode after spinal anaesthesia. Consecutive patients ( n = 258) who had had surgery under spinal anaesthesia were studied. Of 42 patients with a previous history of PDPH, eight (19.0±) developed a new PDPH episode; whereas out of 216 without a previous history of PDPH, only 15 (6.9±) presented with PDPH. Previous PDPH history indicates a higher chance of a new episode of PDPH after spinal anaesthesia. Women are more susceptible to such recurrences.

Abstract
Three hundred forty-two subjects underwent 428 research lumbar punctures for studies of cerebrospinal fluid (CSF) biomarkers. Subjects were 67 Alzheimer disease or mild cognitive impairment (AD/MCI) patients and 275 cognitively normal adults aged 21 to 88. Lumbar puncture was performed in the lateral decubitus or sitting position using the Sprotte 24 g atraumatic spinal needle. Up to 34 ml of cerebrospinal fluid were collected. Anxiety and pain experienced during lumbar puncture were rated on a visual analog scale. The frequency of any adverse event (11.7%), clinically significant adverse events (3.97%), and typical post-lumbar puncture headache (PLPHA) (0.93%) was low. Risk of post-lumbar puncture headache was unrelated to age, gender, position during lumbar puncture, ml of cerebrospinal fluid collected, or minutes of recumbent rest following lumbar puncture. The frequency of post-lumbar puncture headache was lower in AD/MCI (P = 0.03) than any other subject group. Anxiety and pain ratings were low. Younger subjects reported more anxiety than old (P = 0.001) and AD/MCI subjects (P = 0.008) and more pain than older normal subjects (P = 0.013). Pain ratings for women were higher than those for men (P = 0.006). Using the Sprotte 24 g spinal needle, research lumbar puncture can be performed with a very low rate of clinically significant adverse events and with good acceptability in cognitively impaired persons and cognitively normal adults of all ages.

Abstract
UNLABELLED In this study, we examined the characteristics of a newly designed spinal needle (Ballpen [B]) with a pencil-like tip formed by a stylet that is withdrawn after penetration of the dura. The main goal was to examine whether the use of the B needle could reduce performance time by improved puncture conditions in comparison with the Sprotte (S) needle. Seven-hundred patients at 4 hospitals received single-dose spinal anesthesia with a 25-gauge B or S needle and 0.5% bupivacaine. The performance time of spinal anesthesia was defined as the time between insertion of the introducer needle and the first identification of cerebrospinal fluid in the hub of the spinal needle. Failed spinals were assessed when patients required general anesthesia. On postoperative Day 2-4, all patients were visited and interviewed. Groups did not differ with respect to demographics, puncture site, and dose of bupivacaine. Performance time was 98 +/- 145 s in Group B and 103 +/- 159 s in Group S (P = 0.68). The failure rate in Groups B and S was 3.8% and 3.9%, respectively, and the incidence of postdural puncture headache was 1.8% and 0.9% (P = 0.50), respectively. We conclude that there was no difference in technical variables or outcome between the B and S needles. IMPLICATIONS This multicenter study examined characteristics of the newly designed Ballpen needle with the Sprotte needle in 700 patients undergoing lower abdominal or extremity surgery in single-dose spinal anesthesia. Technical variables and side effects were comparable between both noncutting spinal needles.

Abstract
The incidences of mortality and morbidity associated with anaesthesia were reviewed. Most of the published incidences for common complications of anaesthesia vary considerably. Where possible, a realistic estimate of the incidence of each morbidity has been made, based on the best available data. Perception of risk and communication of anaesthetic risk to patients are discussed. The incidences of anaesthetic complications are compared with the relative risks of everyday events, using a community cluster logarithmic scale, in order to place the risks in perspective when compared with other complications and with the inherent risks of surgery. Documentation of these risks and discussion with patients should allow them to be better informed of the relative risks of anaesthetic complications. Depending on specific comorbidities and the severity of operation, these risks associated with anaesthesia may increase for any one individual.

Abstract
PURPOSE Postdural puncture headache (PDPH) is an iatrogenic complication of neuraxial blockade. We systematically reviewed the literature on parturients to determine the frequency, onset, and duration of PDPH. METHODS Citations on PDPH in the obstetrical population were identified by computerized searches, citation review, and hand searches of abstracts and conference proceedings. Citations were included if they contained extractable data on frequency, onset, or duration of PDPH. Using meta-analysis, we calculated pooled estimates of the frequency of accidental dural puncture for epidural needles and pooled estimates of the frequencies of PDPH for epidural and spinal needles. RESULTS Parturients have approximately a 1.5% [95% confidence interval (CI) 1.5% to 1.5%) risk of accidental dural puncture with epidural insertion. Of these, approximately half (52.1%; 95% CI, 51.4% to 52.8%) will result in PDPH. The risk of PDPH from spinal needles diminishes with small diameter, atraumatic needles, but is still appreciable (Whitacre 27-gauge needle 1.7%; 95% CI, 1.6% to 1.8%). PDPH occurs as early as one day and as late as seven days after dural puncture and lasts 12 hr to seven days. CONCLUSION PDPH is a common complication for parturients undergoing neuraxial blockade.

Abstract
In maternity units in which central neuraxial techniques are frequently used, newer methods of epidural drug delivery (continuous infusion, patient-controlled) are well established and combined spinal-epidural analgesia is commonly used. Continuous spinal analgesia has reemerged as a useful approach after accidental dural puncture. Lumbar sympathetic block has been revisited and the safety of paracervical nerve block improved. The analgesic properties of systemic opioid in labor are poor, but PCIA at least has psychological benefits and allows rapid drug titration. PCIA is again under investigation because of the potent antinociceptive effects of the short-acting mu-opioid agonist, remifentanil. The premixing of nitrous oxide and a subanesthetic concentration of volatile anesthetic for patient-controlled administration has been tested under control of midwifery staff and without direct medical supervision.

Abstract
The combined spina-epidural (CSE) technique has become increasingly popular for labor analgesia. The advantages of the CSE include more rapid onset of analgesia, reduced total drug dosage, minimal or no motor blockade, and increased patient satisfaction. CSE has also been associated with more rapid cervical dilation when compared to epidural analgesia in nulliparous women in early labor. Despite these potential advantages, the indications for CSE versus epidural analgesia remain unclear and controversial. This review should allow better understanding of the benefits and risks of this technique, and bearing in mind that no ultimate neuraxial analgesic exists, it would seem that CSE should be considered a major breakthrough in the management of labor analgesia.

Abstract
A retrospective review of obstetric anaesthesia charts was performed for all parturients receiving regional anaesthesia over a 22-month period. The incidence of headache, post dural puncture headache (PDPH) and various other complications of regional anaesthesia that had been prospectively assessed were noted, as was the anaesthetic technique used (epidural or combined spinal epidural (CSE)). PDPH was rare (0.44%) and occurred with similar frequency in those managed with either epidural or CSE anaesthesia or analgesia. The pencil-point spinal needle gauge (27 or 29) did not influence the incidence of PDPH. Following a CSE technique, the epidural catheter more reliably produced effective analgesia/anaesthesia as compared with a standard epidural technique (1.49% versus 3.18% incidence of replaced catheters respectively). We conclude, based on the results of this retrospective review, that CSE is acceptable with respect to the occurrence of PDPH and that it is possible it is advantageous in relation to the correct placement of the epidural catheter

Abstract
Needle size and shape may influence the incidence of paresthesias, post-dural puncture headache and other complications during combined spinal-epidural (CSE) procedures. We have noted a relatively high incidence of transient paresthesias during placement of the spinal needle during CSE for labor analgesia. The purpose of this study was to compare the occurrence of paresthesia and post-dural puncture headache in parturients who received CSE analgesia with either a 25-gauge or 27-gauge Whitacre needle. In a prospective observational study, data were gathered from 478 consecutive women receiving labor analgesia. Incidence, duration, and character of any paresthesias upon spinal needle placement and the incidence and treatment of headache were recorded. The incidence of paresthesia with the two needles was similar (16% with 25-gauge vs 15.4% with 27 gauge) but the incidence of post-dural puncture headache was higher with the 25-gauge needle (4% vs 0.7% with 27 gauge, P < 0.05). Our data suggest that with Whitacre needles, 27-gauge might be preferable to 25-gauge needles to reduce the rate of post-dural puncture headache in parturients but that they do not alter the incidence of transient paresthesias.

Abstract
Immediate and long-term symptoms, particularly headache, are recognised complications of dural puncture. To investigate long-term symptoms, a case-controlled retrospective questionnaire study was performed. The questionnaire was sent to 194 mothers who had suffered either accidental dural puncture during the placement of an epidural catheter or had developed a significant headache following spinal anaesthesia. The mothers were questioned about the nature and severity of symptoms and the impact upon their normal daily lives. They were also asked about the type and efficacy of any treatment they had received for these symptoms. An equal number of controls matched for ethnicity, age, modes of delivery and needle type were also questioned. There was increased reporting of new long-term headache and neckache in the spinal study group and an increased reporting of new long-term backache in the accidental dural puncture group compared to the epidural controls. These symptoms had a significant impact upon the mother's daily life and in some instances lasted for years. Disappointingly, although epidural blood patching was beneficial in the short term, it failed to produce any reduction in the incidence of long-term symptoms.

Abstract
PURPOSE To describe obstetric anesthesia in Canada as practiced in 1997: to identify practices at variance with the literature and the opinions of experts: and to identify questions for future research. METHODS In 1997, a detailed postal questionnaire asking about the practice of obstetric anesthesia was mailed to all 1,539 specialist anesthesiologist members of the Canadian Anaesthetists' Society residing in Canada. Nonresponders were mailed a second questionnaire three months later RESULTS There were 865 completed questionnaires returned for analysis (56.2%). Of these, 522 anesthesiologists practiced obstetric anesthesia (60.3%). The data were subdivided into those from anesthesiologists with a full or part-time university based practice (40.1%) and those from a community based practice (59.9%). University based and community-based anesthesiologists have very similar patterns of practice. Specific areas where anesthesia practice was different from current recommendations included: (1) information provided when obtaining consent for labour epidural analgesia, (2) use of opioids and local anesthetics for initiation of epidural analgesia, (3) use of coagulation testing in preeclampsia, (4) the common use of cutting spinal needles, (5) use of neuraxial morphine and nonsteroidal anti-inflammatory agents after Cesarean deliveries, (6) optimal treatment of neuraxial opioid side effects, (7) when to insert an endotracheal tube for general anesthesia after delivery, and (8) withdrawing epidural catheters through epidural needles. CONCLUSIONS This survey presents reference data on the practice of obstetric anesthesia in Canada in 1997. Anesthesiologists with university affiliation have very similar practices to those without university affiliations.

Abstract
Concern has been expressed that recent changes in techniques of spinal blockade may have resulted in an increase in frequency of neurological sequelae. In order to make preliminary enquiries about anaesthetists' recent experiences of neurological sequelae following spinal and combined spinal-epidural anaesthesia, a questionnaire, covering numbers of procedures, needles used and any neurological problems that had been encountered, was sent to the anaesthetist in charge of each obstetric centre on the Royal College of Obstetricians and Gynaecologists' United Kingdom list. Replies were received from 222 of the 259 units, of whom 40 reported a total of 56 cases involving prolonged neurological sequelae, of which nine were probable obstetric palsies, 18 could be attributed to the regional procedure (one instance of conus damage and the rest largely sensory disturbances) and 29 were of uncertain origin, including a second conus damage. There was no obvious difference in incidence of problems associated with combined spinal-epidural vs. the single-shot spinal technique (odds ratio 1.14, confidence interval 0.53 to 2.46), or Sprotte vs. Whitacre atraumatic needle (odds ratio 1.40, confidence interval 0.64 to 3.08). A prospective survey, or better still, randomisation would be needed to verify these findings.

Abstract
BACKGROUND In adults, pencil-point spinal needles are believed to be less traumatic and therefore to be superior compared to cutting-point needles with respect to success rate and postpuncture complications. The aim of this randomised, parallel groups and prospective study was to record the success rate and to evaluate the incidence of complications following spinal anaesthesia with the two types of needles in children. METHODS We studied 215 children aged 1 to 18 years. A 25-gauge needle was used in children up to 7 years (n=96) and a 27-gauge needle in older children (n=119). During lumbar puncture with either a cutting-point (n=109) or a pencil-point (n=106) spinal needle, we recorded puncture characteristics and the success of cerebrospinal fluid (CSF) aspiration. Hyperbaric bupivacaine 5 mg ml(-1) at a dose of 0.3-0.4 mg kg(-1) was used for the spinal anaesthesia. The incidence of postdural puncture complications was recorded from diaries completed by the children and parents one week after the lumbar puncture. RESULTS The success rate of the spinal anaesthesia was 97% without difference between the needles. The success rate was higher when the aspiration of CSF was easy compared to if it was difficult (98% vs. 88%, P=0.02). Two hundred and seven diaries were returned (97%). Twenty-four children developed a headache, 8 of which were classified as a postdural puncture headache (PDPH), 6 with the cutting-point needle and 2 with the pencil-point needle (n.s.). Nine children developed signs of transient radicular irritation with no difference between the needles. CONCLUSION Both types of spinal needles can be used in children, and a free aspiration of CSF results in a high success rate of the spinal block. Postpuncture complications are as common in children as in adults.
