Changes of abdominal wall mechanics and pain after tension-free inguinal hernia repair with polypropylene mesh / 中国组织工程研究

BACKGROUND: Chronic pain after tension-free inguinal hernia repair is a common postoperative complication. An important cause of chronic pain is nerve injury. OBJECTIVE: To observe the effect of iliohypogastric nerve preposition on chronic pain after inguinal hernia repair and analyze its mechanics. METHODS: Totally 76 male inguinal hernia patients, from August 2013 to November 2016, aged 36-95 years in Second People’s Hospital of Lianyungang were selected. The patients were all treated with large-size polypropylene non-absorbable mesh insertion. The iliohypogastric nerve was placed in front of the mesh. Pain was followed up at 3, 6, and 12 months after operation. This study was approved by the Ethics Committee of Second People’s Hospital of Lianyungang. RESULTS AND CONCLUSION: (1) No chronic pain or recurrence was found in the 76 patients at 3, 6 and 12 months after surgery. (2) The pressure included vertical pressure and tangent pressure formed from intra-abdominal pressure on abdominal wall, directly affecting abdominal wall and artificial repair materials. This was the basic cause of the relative mechanical relationship between nerve and mesh. (3) The results showed that the tension-free inguinal hernia repair with the iliohypogastric nerve preposition could reduce the incidence of postoperative chronic pain, which may be related to the effect of postoperative abdominal pressure on tissue repair, especially the repair around the mesh.

Ultrasound guided nerve block versus caudal block for post-operative analgesia in children undergoing unilateral groin surgery

Background: Pain is an unpleasant subjective sensation which can only be experienced and not expressed, especially in children. The primary reason to treat or prevent pain is humanitarian. Aim and objectives: To assess Ultrasound Guided Ilioinguinal / Iliohypogastric nerve block versus Caudal block for post-operative analgesia in children undergoing unilateral groin surgery in ASA grade I and II children. Materials and methods: Sixty patients aged between 3-12 years undergoing unilateral groin surgery were included. The objectives of this study were to compare the effects of caudal block and ultrasound guided Ilioinguinal/ Iliohypogstric nerve block in terms of duration of analgesia, quality of analgesia and hemodynamic. Results: The mean age of two groups was comparable with Mean ± SD 4.67 ± 1.4 for B group and Mean ± SD 4.7 ± 1.34 for C group, which was statistically not significant. In the present study, major number of cases came for herniotomy being 47% of total cases in both groups followed by high ligation 27% in US II/IH nerve block,23% in cauadal group, and orchidopexy 27% in II/IH nerve block group and 30% in caudal group. Mean duration of surgery of B group was 28.17±8.56 minutes, and for C group was 29.67±8.60 minutes. The difference between the means was statistically not significant (P>0.05). The baseline, intra operative heart rate changes between two groups were comparable and were statistically not significant and therapeutic interventions were not T. Ravi, N.

Duration of Postoperative analgesia is comparable in both the groups with Mean±SD values being 4.95±0.51 for B group and 4.78±0.49 for C group which is statistically not significant with PValue being >0.05. Conclusion: Ultrasound guided Ilioinguinal / Iliohypogastric nerve blocks is an ideal procedure for unilateral groin surgeries in children, regarding quality of analgesia with less pain scores and duration of analgesia is comparable with that of caudal block, with lower volume of local anesthetic.

Ilioinguinal and iliohypogastric nerve block / Монголын Анагаах Ухаан

Ilioinguinal (II) and iliohypogastric (IH) nerve blocks are often performed to provide intra- andpostoperative analgesia for hernia repair in children and adults. Several techniques are describedin the literature. Recently an ultrasound guided technique for II and IH nerve blocks were describedin the international journals. The block success rates are variable specially for using anatomicallandmark blind techniques. In the present study, the anatomical variations in course of the II andIH nerves are described. Knowledge of the course of these nerves in the inguinal region, and anunderstanding of variations seen in their topography, can decrease the incidence of postoperativecomplications and adverse effects. Ultrasound guidance of block performance will shorten the time,reduce the number of needle passes and shorten the block onset time. Blocks may be performedusing lower local anesthetic doses.

Continuous Ilioinguinal-iliohypogastric Nerve Block for Groin Pain in a Breast-feeding Patient after Cesarean Delivery

Ilioinguinal and iliohypogastric (II/IH) nerve injury is one of the most common nerve injuries following pelvic surgery, especially with the Pfannenstiel incision. We present a case of intractable groin pain, successfully treated with a continuous II/IH nerve block. A 33-year-old woman, following emergency cesarean section due to cephalopelvic disproportion, presented numbness in left inguinal area and severe pain on the labia on the second postoperative day. The pain was burning, lancinating, and exacerbated by standing or movement. However, she didn't want to take additional medicine because of breast-feeding. A diagnostic II/IH nerve block produced a substantial decrease in pain. She underwent a continuous II/IH nerve block with a complete resolution of pain within 3 days. A continuous II/IH nerve block might be a goodoption for II/IH neuropathy with intractable groin pain in breast-feeding mothers without adverse drug reactions in their infants.

Revision of loop colostomy under regional anaesthesia and sedation

Patients presenting for emergency abdominal procedures often have medical issues that cause both general anaesthesia and central neuraxial blockade to pose significant risks. Regional anaesthetic techniques are often used adjunctively for abdominal procedures under general anaesthesia, but there is limited published data on procedures done under peripheral nerve or plexus blocks. We herein report the case of a patient with recent pulmonary embolism and supraventricular tachycardia who required colostomy refashioning. Ultrasonography-guided regional anaesthesia was administered using a combination of ilioinguinal-iliohypogastric, rectus sheath and transversus abdominis plane blocks. This was supplemented with propofol and dexmedetomidine sedation as well as intermittent fentanyl and ketamine boluses to cover for visceral stimulation. We discuss the anatomical rationale for the choice of blocks and compare the anaesthetic conduct with similar cases that were previously reported.

Iliohypogastric/ilioinguinal nerve block in inguinal hernia repair for postoperative pain management: comparison of the anatomical landmark and ultrasound guided techniques / Bloqueio dos nervos ílio-hipogástrico/ilioinguinal em correção de hérnia inguinal para tratamento da dor no pós-operatório: comparação entre a técnica de marcos anatômicos e a guiada por ultrassom / Bloqueo de los nervios ileohipogástrico/ilioinguinal en corrección de hernia inguinal para el tratamiento del dolor en el postoperatorio: comparación entre la técnica de marcas anatómicas y la guiada por ultrasonido

Objectives: The purpose of this study is to compare the efficacy of iliohypogastric/ilioinguinal nerve blocks performed with the ultrasound guided and the anatomical landmark techniques for postoperative pain management in cases of adult inguinal herniorrhaphy. Methods: 40 patients, ASA I-II status were randomized into two groups equally: in Group AN (anatomical landmark technique) and in Group ultrasound (ultrasound guided technique), iliohypogastric/ilioinguinal nerve block was performed with 20 ml of 0.5% levobupivacaine prior to surgery with the specified techniques. Pain score in postoperative assessment, first mobilization time, duration of hospital stay, score of postoperative analgesia satisfaction, opioid induced side effects and complications related to block were assessed for 24 h postoperatively. Results: VAS scores at rest in the recovery room and all the clinical follow-up points were found significantly less in Group ultrasound (p < 0.01 or p < 0.001). VAS scores at movement in the recovery room and all the clinical follow-up points were found significantly less in Group ultrasound (p < 0.001 in all time points). While duration of hospital stay and the first mobilization time were being found significantly shorter, analgesia satisfaction scores were found significantly higher in ultrasound Group (p < 0.05, p < 0.001, p < 0.001 respectively). Conclusion: According to our study, US guided iliohypogastric/ilioinguinal nerve block in adult inguinal herniorrhaphies provides a more effective analgesia and higher satisfaction of analgesia than iliohypogastric/ilioinguinal nerve block with the anatomical landmark technique. Moreover, it may be suggested that the observation of anatomical structures with the US may increase the success of the block, and minimize the block-related complications. .

A Comparison between Ilioinguinal and Iliohypogastric Nerve Block and Infiltration of Local Anesthetics for Postoperative Pain after Inguinal Herniorrhaphy in Children / 소아외과

The present study compared the postoperative analgesic effects of ilioinguinal and iliohypogastric nerve block with infiltration of local anesthetics (bupivacaine) into the wound in children after inguinal hernia repair. Ninety children below 7 years old who were scheduled elective inguinal hernia repair were randomly allocated into one of three groups. The patients in nerve block (NB) group, ilioinguinal and iliohypogastric nerve block was done with 0.5 mL/kg of 0.25% bupivacaine. The patients in infiltration of local anesthetics (LI) group, 0.5 mL/kg of 0.25% bupivacaine was infiltrated into the wound after surgery. The patients in control group were allocated as a Control group. Postoperative pain was assessed at 1, 3, 5, and 24 hours after operation with FLACC scale and additional analgesic consumption were counted. The three groups were not significantly different in age, sex, body weight, and duration of operation. Pain scores at 1 hour and 3 hours after operation were significantly higher in Control group than in NB group and LI group (p<0.01), whereas there were no difference between NB group and LI group. The rescue analgesics administration was significantly higher in Control group (n=11) than in NB group (n=6) and LI group (n=7) (p<0.05). There were 2 cases of transient femoral nerve palsy in NB group. Both of ilioinguinal and iliohypogastric nerve block and infiltration of local anesthetics into the wound provided effective postoperative analgesia in early postoperative period following inguinal hernia repair in children. But no difference between the two methods. Technically, infiltration of local anesthetics into the wound was easier and safer than ilioinguinal and iliohypogastric nerve block.

Combined epidural anesthesia and ultrasound guided peripheral nerve block for wound revision in a patient with peripartum cardiomyopathy: A case report / 대한마취과학회지

Peripartum cardiomyopathy (PPCM) is a rare complication that occurs between the late stage of pregnancy and six months after delivery. PPCM presents as symptoms of left ventricular dysfunction and it can be fatal unless treated promptly. Furthermore, anesthesia and surgery in such patients is a large challenge to anesthesiologists. First and foremost, the maintenance of stable hemodynamics is a major concern. We report a case of combined lumbar epidural anesthesia and both ilioinguinal and iliohypogastric nerve block under ultrasound guided for a wound revision in a 37-year-old woman diagnosed with PPCM after an emergency cesarean section.

Bilateral Ilioinguinal and Iliohypogastric Nerve Blockade for Analgesia after Surgery through a Pfannenstiel Incision / 대한마취과학회지

BACKGROUND: Epidural administration of morphine is a common method for postoperative analgesia in the lower abdominal surgery, but many complications can be produced. Since the pfannenstial incision lies within L1 dermatome, bilateral ilioinguinal and iliohypogastric nerve blocks(IINB) should provide analgesia after surgery through that incision. METHODS: Forty patients undergoing cesarean delivery or total abdominal hysterectomy(TAH) through a pfannenstiel incision were randomly assigned to one of two groups: epidural morphine group(n=20) received 3 mg of morphine epidurally after surgery with epidural anesthesia; IINB group(n=20) performed IINB with 0.5% bupivacaine, 10 ml to each side after surgery with general anesthesia. Visual analogue scale(VAS) scores at resting and moving state, and complications were checked at 0, 2, 4, 8, 12, 24 hours after surgery. RESULTS: Postoperative VAS scores did not show significant differences between the two groups at rest after 0, 2, 4, 8, 12, 24 hours and at moving state after 0, 2, 4 hours, but IINB group had less pain with movement than epidural morphine group at 8, 12, 24 hours after surgery(p<0.05). The incidence of pruritus was rare in IINB group(P<.05), but incidences of other complications were not significantly different between the two groups. CONCLUSIONS: IINB is effective for analgesia after surgery through a pfannenstiel incision because of a lower incidence of complications and less postoperative pain with movement than epidural morphine, and can be performed to patients who have contraindications and difficulty for epidural analgesia.
