  • Nerve Stimulator and multiple injection technique for upper and lower limb blockade failure rate patient acceptance and neurologic complications
    Anesthesia & Analgesia, 1999
    Co-Authors: G Fanelli, A Casati, P Garancini, G Torri
    Abstract:

    To evaluate the failure rate, patient acceptance, effective volumes of local anesthetic solution, and incidence of neurologic complications after peripheral Nerve block performed using the multiple injection technique with a Nerve Stimulator, we prospectively studied 3996 patients undergoing combine

  • Nerve Stimulator and multiple injection technique for upper and lower limb blockade failure rate patient acceptance and neurologic complications study group on regional anesthesia
    Anesthesia & Analgesia, 1999
    Co-Authors: G Fanelli, A Casati, P Garancini, G Torri
    Abstract:

    UNLABELLED: To evaluate the failure rate, patient acceptance, effective volumes of local anesthetic solution, and incidence of neurologic complications after peripheral Nerve block performed using the multiple injection technique with a Nerve Stimulator, we prospectively studied 3996 patients undergoing combined sciatic-femoral Nerve block (n = 2175), axillary blocks (n = 1650), and interscalene blocks (n = 171). The success rate and mean injected volumes of local anesthetic were: 93% with 22.6 +/- 4.5 mL in the axillary, 94% with 24.5 +/- 5.4 mL in the interscalene, and 93% with 28.1 +/- 4.4 mL in the sciatic-femoral Nerve blocks. Patients receiving combined sciatic-femoral Nerve block showed more discomfort during block placement and worse acceptance of the anesthetic procedure than patients receiving brachial plexus anesthesia. During the first month after surgery, 69 patients (1.7%) developed neurologic dysfunction on the operated limb. Complete recovery required 4-12 wk in all patients but one, who required 25 wk. The only variable showing significant association with the development of postoperative neurologic dysfunction was the tourniquet inflation pressure ( 400 mm Hg, odds ratio 2.9, 95% confidence intervals 1.6-5.4; P 90% with a volume of <30 mL of local anesthetic solution and an incidence of transient neurologic complication of <2%. IMPLICATIONS: Based on a prospective evaluation of 3996 consecutive peripheral Nerve blocks, the multiple injection technique with Nerve Stimulator allows for up to 94% successful Nerve block with <30 mL of local anesthetic solution. Although the data collection regarding neurologic dysfunction was limited, the withdrawal and redirection of the stimulating needle was not associated with an increased incidence of neurologic complications. Sedation/analgesia should be advocated during block placement to improve patient acceptance.

  • a comparison of Nerve Stimulator guided paravertebral block and ilio inguinal Nerve block for analgesia after inguinal herniorrhaphy in children
    Anaesthesia, 2006
    Co-Authors: Z Naja, Mohamad Al-tannir, Fouad Ziade, M Raf, El M Rajab, Nabil Daoud, P A Lonnqvist
    Abstract:

    Summary The aim of this study was to compare the efficacy of Nerve Stimulator guided paravertebral block with ilio-inguinal Nerve block in children undergoing inguinal herniorrhaphy. Eighty children were randomly allocated to receive either paravertebral block or ilio-inguinal Nerve block. Each block was evaluated in terms of intra-operative haemodynamic stability, postoperative pain scores at rest, on movement and during activity, requirement for supplemental analgesia and parental satisfaction. Haemodynamic stability was maintained significantly better during sac traction in the paravertebral block group (p < 0.005). Pain scores and analgesic consumption were significantly lower in the paravertebral block group during the postoperative follow-up period (p < 0.05). Parental satisfaction (93% vs 69%) and surgeon satisfaction (93% vs 64%) were significantly higher in the paravertebral block group (p < 0.05). Paravertebral blockade improved and prolonged postoperative analgesia, and was associated with greater parental and surgeon satisfaction when compared to ilio-inguinal Nerve block.

  • Nerve Stimulator guided pudendal Nerve block versus general anesthesia for hemorrhoidectomy.
    Canadian journal of anaesthesia = Journal canadien d'anesthesie, 2006
    Co-Authors: Z Naja, Mariam El-rajab, Mohamad Al-tannir, Fouad Ziade, Riad Zbibo, Mustafa Oweidat, P A Lonnqvist
    Abstract:

    the hypothesis that patients receiving a Nerve Stimulator guided pudendal Nerve block for hemorrhoidectomy would experience more effective and prolonged postoperative analgesia and shorter hospital stay compared to patients receiving general anesthesia. Methods: This was a prospective randomized observer-blinded study. Following Ethics Committee approval and informed consent, 80 patients scheduled for hemorrhoidectomy were randomized to two groups of 40 patients each: general anesthesia alone, or Nerve Stimulator guided pudendal Nerve block. Postoperative pain, the primary outcome variable of the study, was assessed by visual analogue scale scores at pre-determined intervals during the postoperative period. Analgesic consumption, time to return to normal activities, patients’ and surgeons’ satisfaction, and duration of hospital stay were recorded. Results: The guided pudendal Nerve block group failed in three patients, requiring their conversion to general anesthesia. Otherwise, patients in the pudendal Nerve block group experienced better postoperative pain relief at rest (P < 0.0001), on walking, sitting, and defecation (P < 0.001), reduced need for opioids (11/35 vs 32/37; P < 0.0001), a more rapid return to normal activities (7.2 vs 13.8 days; P < 0.0001) and also a shorter hospital stay (25/35 vs 3/37 outpatient cases; P < 0.0001) compared to the general anesthesia group. Pudendal Nerve block was also associated with overall higher patient satisfaction compared to general anesthesia (30/35 vs 9/37; P < 0.0001). Conclusion: Nerve Stimulator guided pudendal Nerve block is associated with reduced postoperative pain, shortened hospital stay, and earlier return to normal activity compared to general anesthesia for hemorrhoidectomy.

  • Nerve Stimulator guided pudendal Nerve block decreases posthemorrhoidectomy pain
    Canadian Journal of Anaesthesia-journal Canadien D Anesthesie, 2005
    Co-Authors: Z Naja, M F Ziade, P A Lonnqvist
    Abstract:

    Purpose Based on our institution’s initial results that reflected reduced postoperative pain using a modified pudendal Nerve block technique, we conducted a prospective, randomized, double-blind study to investigate whether a combination of general anesthesia and bilateral Nerve Stimulator guided pudendal Nerve blocks could provide better postoperative pain relief compared to general anesthesia alone or in combination with placebo Nerve blocks.

Following Ethical Committee approval and informed consent 90 patients scheduled for hemorrhoidectomy were randomized to three different groups of 30 patients each: general anesthesia alone, general anesthesia plus Nerve Stimulator guided pudendal Nerve block or general anesthesia plus placebo Nerve blocks. Postoperative pain, the primary outcome variable of the study, was assessed by visual analogue scale scores at predetermined time intervals during the postoperative period. Total amount of analgesics, time to return to normal activities and patient satisfaction were also recorded. The pudendal Nerve block group was found to have better postoperative pain-relief (P < 0.005), reduced need for analgesics (P < 0.05), and also a more rapid return to normal activities (P < 0.001) compared to general anesthesia alone or in combination with placebo blocks. The pudendal Nerve block group was also associated with significantly higher patient satisfaction (P < 0.001) compared to the other two groups. A combination of general anesthesia and Nerve Stimulator guided pudendal Nerve block showed significantly reduced postoperative pain, shortened hospital stay, and earlier return to normal activity. Thus, this technique deserves more widespread use in patients undergoing hemorrhoidectomy.
