A prospective, blind, randomised trial was undertaken to determine if the incidence of postlumbar puncture headache is significantly altered by 24 hours' recumbency. One hundred and two patients were allocated randomly to rest supine in bed for either 4 or 24 hours after spinal anaesthesia for urological or gynaecological surgery. A standardised spinal anaesthetic technique was applied that incorporated the use of a 22-gauge needle. All patients were followed-up prospectively to determine if there was a difference in the incidence of postlumbar puncture headache between the two groups. Five patients (11.6%) who were recumbent for 4 hours developed postlumbar puncture headache, a result which was not statistically significantly different from the seven patients (11.9%) in the other group who complained of postlumbar puncture headache. Diagnostic lumbar puncture was performed on 76 neurological inpatients. They were randomly allocated to one of four bed rest positions for four hours following the procedure (supine and horizontal, prone and horizontal, supine with head-down tilt and prone with head-down tilt) after which they were allowed to get up. There was no substantial or significant difference in the incidence of headache between the four groups. Expectation of headache did not appear to be an important factor in its development. A prospective, randomised, double-blind trial was conducted to study the effect of epidural morphine in prevention of post dural puncture headache in 25 parturients after inadvertent dural puncture. Women were randomly allocated to receive two epidural injections, 24 h apart, of either 3 mg morphine in 10 ml saline (morphine group) or 10 ml saline (saline group). The incidence of headache and need for therapeutic epidural blood patch were reported. There was a significant difference in the incidence of headache between the two groups: 3/25 (12%) in the morphine group and 12/25 (48%) in the saline group (p = 0.014). Therapeutic epidural blood patches were required in six patients in the saline group and none of the patient in the morphine group (p = 0.022). It was concluded that epidural morphine appears to be a simple and effective technique for prevention of post dural puncture headache after accidental dural puncture in high risk obstetric patients. A randomised double blind controlled trial of 'epidural blood-patch' as treatment for post-dural puncture headache is presented. The method was successful in 11 out of 12 cases on its first application, the twelfth patient being relieved by a second procedure. None of six patients reported benefit from a 'sham' procedure. The rationale for the use of the technique is discussed. To evaluate the efficacy of a prophylactic saline patch and a prophylactic blood patch in prevention of headache following accidental dural puncture in obstetric patients.
                Prospective, randomized, single-blind study on dural puncture headache occurrence and cessation.
                Inpatient obstetric unit at a metropolitan medical center.
                Seventy-four inpatients who underwent vaginal delivery or cesarean section following accidental dural puncture during administration of epidural anesthesia for labor and delivery.
                Group 1 (n = 24), the control group, received fluids and analgesics. Group 2 (n = 30) received prophylactic epidural saline (40 to 60 ml) through the epidural catheter following completion of the obstetric procedure. Group 3 (n = 20) received autologous blood (15 ml) via epidural catheter following completion of the obstetric procedure.
                In Group 1, 21 of 24 patients (87.5%) developed headaches, with conservative management. In Group 2, 20 of 30 patients (66.7%) developed headaches, and in Group 3, 1 of 20 patients (5%) developed a headache.
                The results of this study suggest that the administration of a prophylactic epidural blood patch is highly effective in the prevention of headaches following dural puncture, with headache frequency reduced from 87.5% to 5%. 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.
                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.
                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.
                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. To determine the efficacy of epidural blood patch (EDBP) for the treatment of post dural puncture headache (PDPH).
                We randomised 42 patients who presented with PDPH, lasting 24 h to 1 week, to receive EDBP (n = 19) or conservative treatment (n = 23). The primary end point was any headache at 24 h after the start of treatment. Secondary end points were presence and severity of headache after 1 week. Stratified Mantel-Haenzel analysis was used to adjust for confounders.
                Two patients refused to participate directly after randomisation and allocation to conservative treatment. They were excluded from the study. At 24 h after the start of treatment, headache was present in 11 (58%) patients allocated to EDBP and in 19 (90%) patients allocated to conservative treatment (RR 0.64, 95% CI 0.43 to 0.96). At day 7, headache was present in three (16%) patients allocated to EDBP and in 18 (86%) allocated to conservative treatment (RR 0.18, 95% CI 0.06 to 0.53). Headache was mild in all three EDBP patients, but in 10 of 18 conservatively treated patients who had not recovered by day 7 it was classified as moderate or severe. Adjustments for confounders did not affect these results.
                EDBP is an effective treatment for PDPH. It offers complete resolution of symptoms in a large proportion of patients. In the remaining patients, it reduces headache severity and allows them to return to their everyday activities. Spinal anesthesia is major complication is Post-Dural Puncture Headache (PDPH) which is an intense and debilitating event. We decided to assess if intravenous administration of dexamethasone can decrease the incidence and/or intensity of this kind of headache. For this purpose 178 patients, who were supposed to undergo lower extremity orthopedic surgery, were enrolled in the study . Before spinal anesthesia was initiated, the first group (DXM-group) received 2 mL intravenous (i.v) dexamethasone whereas the second group (PCB-group) received 2 mL i.v. normal saline. After termination of surgery, a 7 days follow-up started to observe the possible occurrence and intensity of PDPH. There was no statistically significant difference between DMX and PCB groups regarding the incidence of PDPH. However, the intensity of headache differed between the two groups being less severe if IV dexamethasone had been given prophylactically. Dexamethasone can be used to decrease the severity of PDPH in patients who receive spinal anesthesia. The prevention of postdural puncture headache after spinal anaesthesia for extracorporeal shockwave lithotripsy was investigated by a controlled clinical trial which compared epidural injection of 10 ml of autologous blood with 10 ml of normal saline immediately after intrathecal injection of local anaesthetic. The incidence of postdural puncture headache was 8.3% in the group that received blood compared with 45% in the group that received saline, a significant reduction (p less than 0.01). The incidences of backache and lower limb paraesthesiae were similar in both groups. No serious complications were reported.
There is no good evidence from randomised trials to suggest that routine bed rest after dural puncture is beneficial. The role of fluid supplementation in the prevention of post-dural puncture headache remains uncertain.
