Efficacy of superficial cervical plexus block versus cervical retrolaminar block both combined with auriculotemporal nerve block in parotid surgeries.

Background: Regional techniques in parotid surgeries include superficial cervical plexus block (SCPB) and auriculotemporal nerve (ATN) block, which can be used as an anesthetic technique for awake parotidectomy. This study aimed to evaluate the efficacy of cervical retrolaminar block (RLB) as an alternative to SCPB both, used in combination with auriculotemporal nerve (ATN) block, in parotid surgery. Material and methods: A total of 40 patients undergoing parotid surgery were prospectively randomized into either the SCPB group (n = 20) or the cervical RLB group (n = 20) using 20 ml of 0.25% bupivacaine plus 5 mcg\mL epinephrine. Both were combined with ATN block using 5 ml of 0.25% bupivacaine plus 5 mcg\mL epinephrine. Results: The time to first request for analgesia was longer in the RLB group than the SCPB group. Total intra operative fentanyl consumption and post-operative pethidine consumption in the first 24h were lower in group RLB. All patients (n = 20) in the SCPB group required rescue analgesia using pethidine, while only 40% of patients required pethidine in the RLB group. Visual analog scale was lower in the RLB group from 2 to 24-h post-operatively, but it was associated with hypotension and longer block technique time occurred with RLB than SCPB. There was no significant difference in side effects except for 20% Horner's syndrome in the SCPB group. Conclusion: Cervical RLB is more effective analgesic technique than SCPB, as the cervical RLB showed longer time to first analgesic request, lower intraoperative anesthetic consumption, lower total post-operative pethidine consumption and lower VAS.

High-volume, multilevel local anesthetics-Epinephrine infiltration in kyphoscoliosis surgery: Intra and postoperative analgesia.

BACKGROUND AND AIMS: Local anesthetic (LA) infiltration is one of the analgesic techniques employed during scoliosis correction surgery. However, its efficacy is controversial. In the present study for optimizing analgesia using the infiltration technique, we proposed two modifications; first is the preemptive use of high volume infiltration, second is applying three anatomical multilevel infiltrations involving the sensory, motor, and sympathetic innervations consecutively. MATERIAL AND METHODS: This prospective study involved 48 patients randomized into two groups. After general anesthesia (GA), the infiltration group (I) received bupivacaine 0.5% 2 mg/kg, lidocaine 5 mg/kg, and epinephrine 5 mcg/mL of the total volume (100 mL per 10 cm of the wound length) as a preemptive infiltration at three levels; subcutaneous, intramuscular, and the deep neural paravertebral levels, timed before skin incision, muscular dissection, and instrumentation consecutively. The control group (C) received normal saline in the same manner. Data were compared by Mann-Whitney, Chi-square, and t-test as suitable. RESULTS: Intraoperatively, the LA infiltration reduced fentanyl, atracurium, isoflurane, nitroglycerine, and propofol consumption. Postoperatively, there was a 41% reduction in morphine consumption, longer time to the first analgesic request, lower VAS, early ambulation, and hospital discharge with high-patient satisfaction. CONCLUSION: The preemptive, high-volume, multilevel infiltration provided a significant intra and postoperative analgesia in scoliosis surgery.

Gigantic submandibular pleomorphic adenoma: A rare case report.

INTRODUCTION: Pleomorphic adenoma (PA) is the most common benign salivary gland tumor. When neglected on some occasions, its size and weight can enormously augment. CASE PRESENTATION: We report a case of a giant submandibular pleomorphic adenoma in a 75 years old female patient which measured 34 × 26 × 20 cm and weighed 8.1 kg. CONCLUSION: Neglecting such tumors without treatment, can cause severe facial disfigurement and can even hinder the airway.

High-volume, Multilevel Local Anesthetics-Epinephrine Infiltration in Kyphoscoliosis Surgery: Blood Conservation.

INTRODUCTION: Scoliosis surgery is usually associated with severe bleeding. Various systemic strategies for blood conservation were applied, while the local techniques get less attention. The preemptive use of sufficient volume for proper tissue infiltration at two levels was applied. The local epinephrine may control bleeding without reliance upon deliberate hypotension, permitting a higher tissue perfusion. MATERIALS AND METHODS: This prospective study included 46 patients scheduled for posterior spinal fusion for scoliosis correction. Patients were randomized into two groups. group I received a cocktail of high volume (100 ml/each 10 cm of wound length) of local anesthetics and epinephrine tumescent infiltration at the subcutaneous (SC) followed by intramuscular level bilaterally. Group C received saline infiltration in the same technique. Statistically, data were analyzed according to its distribution using the t-test, Mann-Whitney, and Chi-square tests as appropriate. RESULTS: There was a significant reduction in blood loss (38%), reduced blood and fluid transfusion (36% and 23%), and reduced operative time (23%), with higher surgeon satisfaction. The surgical field visibility (Fromme's scale) was much better during SC and muscular dissection in Group I, while it was fair during the bony work. The satisfactory field in spite of higher mean blood pressure in Group I greatly omitted the reliance upon deliberate hypotension. CONCLUSION: The high-volume multilevel infiltration of epinephrine cocktail can provide a significant blood and operative time conservation in kyphoscoliosis surgery.

A comparative study between interlaminar nerve root targeted epidural versus infraneural transforaminal epidural steroids for treatment of intervertebral disc herniation.

BACKGROUND: Low back pain (LBP) is one of the most common musculoskeletal abnormalities. Epidural corticosteroid injections (ESIs) have been used long time ago for treatment of lumbar radiculopathy or discogenic back pain in case of failed medical and conservative management. Different techniques for ESIs include the interlaminar, the caudal, and the transforaminal approaches. PURPOSE: The aim of our study is to compare between the efficacy of infraneural transforaminal ESI and lumbar paramedian nerve root targeted interlaminar steroid injection in reduction of unilateral radicular pain secondary to disc prolapse. PATIENTS AND METHODS: This prospective double-blind randomized study was performed on 40 patients randomized into two equal groups, each of 20: the infraneural transforaminal ESI (IN group) and the interlaminar parasagittal ESI (IL group). Patients with backache without leg radiation, or with focal motor neurological deficit, previous spine surgery, S1 radiculopathy, lumbar ESI in the past month, systemic steroid used recently within 4 weeks before the procedure, allergy to any medication or addiction to opioids, and pregnancy were excluded from the study. The duration and efficacy of pain relief (defined as ≥40% reduction of pain perception) by 0-10 visual analog scale (VAS) is the primary outcome. Functional assessment using Modified Oswestry Disability Questionnaire (MODQ) and possible side effects and complications are the secondary outcomes. RESULTS: The VAS and MODQ scores were significantly lower in both groups in comparison with the basal values. There was also a lower VAS in the infraneural group than the parasagittal (IL) group up to 6 months after injection. CONCLUSION: The infraneural (IN) epidural steroid is more favorable than the parasagittal (IL) interlaminar epidural steroid owing to its long-term improvement in physical function than the parasagittal technique with no serious side effects.

Ultrasound-guided bilateral superficial cervical plexus block for thyroid surgery: The effect of dexmedetomidine addition to bupivacaine-epinephrine.

BACKGROUND: The thyroid gland surgery is a common and painful procedure demanding analgesia. Many regional techniques are applied for anterior neck surgeries mostly assigned in relation to the involved cervical fascia. Dexmedetomidine (Precedex) is a selective alpha 2 adrenoceptor agonist which prolongs the sensory blockade duration of local anesthetics. Our study hypothesis is that ultrasound (US)-guided bilateral superficial cervical plexus block (BSCPB) may provide longer analgesia when adding dexmedetomidine to bupivacaine-epinephrine. PURPOSE: The aim of this study is to evaluate the analgesic efficacy and possible side effects of US-guided BSCPB and the effect of dexmedetomidine addition to bupivacaine-epinephrine in patients undergoing thyroid surgery. METHODS: This prospective, double-blind, randomized study was performed on 42 patients randomized into two equal groups each of 21; bupivacaine Group B and dexmedetomidine Group D. Patients with contraindications to regional anesthesia or uncontrolled comorbidities were excluded from the study. Total pethidine consumption in 24 h is the primary outcome. The visual analog scale, timing of the first opioid request, and hemodynamics are the secondary outcomes. RESULTS: In Group D, there was a longer time to the first request of opioid postoperatively, a lower total pethidine consumption and pain score postoperatively, and lower fentanyl requirements intraoperatively. CONCLUSIONS: Sonographic-guided bilateral SCPB using a combination of bupivacaine, dexmedetomidine, and epinephrine was superior to bupivacaine for prolonged analgesia with less intra- and postoperative opioid consumption and lower side effect profile during thyroid surgery.

Tumescent mastectomy: the current indications and operative tips and tricks.

BACKGROUND: Tumescent mastectomy refers to usage of a mixture of lidocaine and epinephrine in a diluting saline solution that makes flaps firm and tense, thus minimizing systemic drugs toxicity and making surgery possible with minimal bleeding. This technique is very useful in elder women and those with American Society of Anesthesiologists; score III and IV. The objective was to establish an alternative safe technique to general anesthesia in some selected mastectomy patients. PATIENTS AND METHODS: Twenty candidate women for total mastectomy and axillary dissection were enrolled and consented to participate. After preparation, an anatomically directed infiltration was made under sedation, using a cocktail of lidocaine, bupivacaine, and epinephrine, followed after 20 minutes by the surgical incision and completion of mastectomy. All intraoperative and postoperative outcomes were recorded. RESULTS: Although 7 cases required added analgesic medications, no conversion for general anesthesia was recorded. Mean operative time was 81±15.8 minutes. Mean blood loss was 95.8±47.5 mL. There was no recorded intraoperative hemodynamic instability. Postoperative visual analog score was not exceeding 4 till the end of the first 24 hours. Opioids were not required in any case, and the mean dosage of Ketorolac used was 30±8.75 mg. Drains output and the incidence of postoperative complications were acceptable. CONCLUSION: We can consider tumescent mastectomy in well-selected patients a safe alternative for performing mastectomy when general anesthesia is hazardous, with minimal blood loss and long lasting postoperative analgesia without an additive effect on the operative time, hospital stay, and intraoperative and postoperative complications.

The feasibility of tissue expanders in reconstruction of giant congenital melanocytic nevi in children.

BACKGROUND: Children with giant congenital melanocytic nevi (GCMN) pose a great challenge to pediatric and reconstructive surgeons because they have to cover the widely exposed area after its excision. A variety of treatment options exist for the management of such cases. In this retrospective review of a selected group of children who had a GCMN of their abdominal walls managed with implantation of tissue expanders (TEs) for staged reconstruction, patients were evaluated with respect to complications and general and esthetic criteria for patient and parent satisfaction. OBJECTIVE: The purpose was to study the feasibility of use of TEs in the management of children who had GCMN, with special emphasis on the complications and children's and parents' satisfaction. MATERIAL AND METHODS: Retrospective data from the 12 patients' charts, operative data of 86 surgical procedures, and follow up visits were analyzed using the Student's t test, and P < .05 was considered statistically significant. RESULTS: In a period of 4 years, from 2004 to 2008, the results of using 37 different sizes of TEs and 86 operative procedures in 12 children (9 boys and 3 girls) aged from 2 to 12 years with different types of abdominal wall GCMN are discussed. CONCLUSION: The TE is a useful and feasible tool for reconstruction of the abdominal wall in cases of GCMN in children. Parents and children are satisfied in general and also with the body image.

Ureterorectostomy as a continent urinary diversion for complicated bladder exstrophy in children by using a modified Duhamel procedure: a case series.

INTRODUCTION: Whatever the method and timing of surgery, a high proportion of children with bladder exstrophy will continue to suffer from urinary incontinence. They face the options of urinary diversion to an external stoma or construction of a neobladder from bowel. This study describes a modified Duhamel's rectal pouch with a ureterorectostomy was carried out on 11 children who had a failed repair of bladder exstrophy. MATERIALS AND METHODS: Ten boys and one girl, aged from 4 to 7 years (mean 5.5), had several unsuccessful operations for bladder exstrophy. All selected to have good renal function and no other anomalies, but were incontinent of urine and had a small contracted or prolapsed bladder. They underwent urinary diversion to the rectum using the Duhamel pullthrough technique, where the sigmoid colon was opened into the back of the anal canal above the dentate line, creating a rectal bladder and making use of the anal sphincter to control urine and stool. All were followed up for 24 months (18-27 months). RESULTS: In this selected group of patients there were no major operative or postoperative complications. Follow-up for 2 years revealed no deterioration in renal function, or electrolytes disturbance. They can hold up to 300 ml of urine and all patients are continent during the daytime with an emptying frequency of 3-5 times. Nocturnal wetting occur some 4-8 times per month with significant decrease with time. Two cases developed pyelonephritis but this was controlled with medical treatment. CONCLUSION: Eleven children achieved effective urinary continence by ureteric diversion to the rectum using a modified Duhamel pullthrough technique. Two years follow up showed no complications, except bed wetting, but long term assessment is warranted.
