Herniorrhaphy is the most common inguinal surgery in children. Several methods such as caudal block, ilioinguinal iliohypogastric block, and wound infiltration have been studied for postoperative pain management in these patients. Caudal block is common in pediatrics. However, ilioinguinal iliohypogastric block is effective and less invasive. Previous studies have shown different comparative results regarding these blocks. This study compares the analgesic effect of caudal and bilateral ilioinguinal iliohypogastric block with ropivacaine in children.

This study is a randomized double-blind clinical trial. A total number of 66 patients aged between 1-7 years that volunteered for bilateral inguinal hernia repair were randomly assigned to two groups. After general anesthesia, caudal block with 1cc/kg ropivacaine 0.2% was performed for 33 patients and sonography-guided ilioinguinal iliohypogastric block with 0.1 cc/kg ropivacaine for each side was considered for another group. Hemodynamic parameters (systolic blood pressure, diastolic blood pressure, and heart rate) during anesthesia, pain score (CHEOPS), delirium score (PAED), nurses’ satisfaction score (RN), need for additional narcotic, recovery time, and complications were compared in these two groups.

There was no statistically significant difference between the two groups in terms of hemodynamic parameters during the anesthesia process. Furthermore, the two groups had no statistically significant difference in CHEOPS score (6.27 in ilioinguinal block and 5.70 in caudal block, P=0.061), PAED score (5.64 vs 5.30, P=0.144), and RN satisfaction score. However, the need for narcotics, mean recovery time, and block complications were comparable in two groups.

Caudal block and ilioinguinal block are equally effective for post herniorrhaphy pain and emergence agitation management in pediatrics. Additionally, no differences were observed in complications. It is recommended that the study be performed with a larger sample size.

 Chronic low back pain (CLBP) is a common issue among older adults. Radicular pain syndromes are often managed with caudal epidural injections. Our study aimed to compare the effects of triamcinolone and magnesium sulfate, used as adjuvants to local anesthetics in caudal blocks, on pain levels and quality of life in patients with LBP.

 A total of 40 patients undergoing caudal block were randomized to two groups,received 10 mL caudal epidural injection of either injection 9 mL of ropivacaine 0.1% and 1 mL of triamcinolone; 40 mg (Group T, n = 20) or magnesium sulfate; 200 mg (group M, n = 20). Improvements in the pain score measured with the Visual Analog Scale (VAS) and functional ability measured with the Oswestry Disability Index (ODI) were the primary and secondary outcome measures, respectively. Before, one month and three months after the caudl block, the VAS and ODI scores were evaluated.

 The VAS and ODI scores did not exhibit a significant difference between the 2 groups at all post-injection time points, except for the VAS score at 3 months, which showed a statistically lower value in group M compared to group T (P = 0.046). However, when comparing within the same group, both groups showed significantly improved VAS and ODI scores at all post-injection time points compared to the pre-injection scores (P < 0.0001).

 The addition of magnesium or triamcinolone to a local anesthetic in caudal epidural injections does not result in any discernible difference. However, this combination may lead to improvements in pain levels and quality of life, and these improvements can be sustained for up to 3 months.

Continuous advancements in ultrasound (US)-guided neuraxial and peripheral nerve blocks (PNB) have allowed the safe and successful use of these blocks as adjuvants to general anesthesia in pediatric patients.

This study was designed to compare the analgesic efficacy of 2 US-guided regional techniques, caudal epidural block (CEB) and subgluteal sciatic nerve block (SNB), in children with cerebral palsy (CP).

The current randomized comparative study was conducted on 30 patients with spastic CP aged 2-12 years who were scheduled for unilateral lower limb multilevel soft tissue corrective surgeries, randomly distributed using a computerized program into 2 equal groups. The CEB group received a US-guided caudal block, and the SNB group received a US subgluteal sciatic nerve block. The time to the first postoperative analgesia requirement (primary outcome), postoperative pain score, total postoperative analgesic consumption, and perioperative complications (secondary outcomes) were assessed in both groups.

The duration of postoperative analgesia was significantly longer in patients of the SNB (14.65 ± 3.08 h) than in the CEB group (5.93 ± 1.68 h). The postoperative pain scores recorded at 6th-12th h and the postoperative 24-h rescue analgesic consumption were significantly lower in the SNB compared to the CEB group.

Ultrasound-guided subgluteal sciatic nerve block is a safe and effective alternative to US-guided caudal analgesia in pediatric patients with spastic CP scheduled for lower limb surgeries, with longer postoperative analgesia and similar perioperative safety profiles.

 One of the methods of pain control after pediatric surgical procedures is regional techniques, including caudal block, despite their limitations.

 In this study, the pain score and complications of caudal tramadol were evaluated in pediatrics following lower abdominal surgery.

 In this study, 46 children aged 3 to 10 years were allocated into two equal groups (R and TR) for performing caudal analgesia after lower abdominal surgery. The injectate contained 0.2% ropivacaine 1 mL/kg in the R group (control group) and tramadol (2 mg/kg) and ropivacaine in the TR group. The pain score, duration of pain relief, amount of paracetamol consumption, hemodynamic alterations, and possible complications at specific times (1, 2, and 6 hours) were evaluated in both groups.

 No considerable difference was observed in the pain score between the groups in the first and second hours (P > 0.05). However, in the sixth hour, the TR group had a significantly lower pain score than the R group (P < 0.05). Compared to the R group, the TR group had a longer period of analgesia and lower consumption of analgesic drugs (P < 0.05). Heart rate and blood pressure differences were not significant between the two groups (P > 0.05). Similarly, the duration of operation and recovery time were not remarkably different between the two groups (P > 0.05). Complications had no apparent differences between these two groups, as well (P > 0.05).

 In this study, the addition of tramadol to caudal ropivacaine in pediatric lower abdominal surgery promoted pain relief without complications.

 Caudal anesthesia is an effective method of pain management, which can be successfully employed to minimize post-thoracotomy pain in pediatric patients. However, its main disadvantage is the short postoperative analgesic period, which can be prolonged by the concurrent administration of one of many adjuvants.

 This prospective randomized, blinded study aimed to compare the efficacy of dexmedetomidine versus morphine as adjuvants to bupivacaine in caudal anesthesia for thoracic surgeries in pediatric patients.

 Fifty patients were randomly allocated into two equal groups. To achieve caudal epidural block anesthesia, the patients in group M (n = 25) were administered morphine and bupivacaine, while group D (n = 25) received a mixture of dexmedetomidine and bupivacaine. The primary outcome of this study was the postoperative analgesic duration achieved. The secondary outcomes included morphine administration in the first 24 hours following caudal block anesthesia, the face, legs, activity, cry, consolability (FLACC) scale scores, and adverse effects, including vomiting, itching, bradycardia, hypotension, and respiratory depression.

 The results showed that patients who had received dexmedetomidine achieved a longer postoperative analgesia as compared to those who had received morphine (P < 0.001). Postoperatively, the heart rate, blood pressure, pain score, and mean consumption of morphine were lower in group D as compared to the group M. There was no significant difference in the adverse effects between the two groups.

 The use of dexmedetomidine as an adjuvant to bupivacaine for caudal anesthesia during pediatric thoracic surgeries induced better and prolonged postoperative analgesia as compared to morphine.
 

 Caudal block is one of the methods of pain management performed following lower abdominal surgery, though having its own limitations.

 In the present study, the effects and side effects of adding dexmedetomidine to ropivacaine in the caudal epidural block were investigated in children after lower abdominal surgery.

 In this randomized, double-blinded clinical trial, 46 children aged three to six years were divided into two groups to perform a caudal block following lower abdominal surgery under general anesthesia. The injectable solution contained ropivacaine in the R group (1 mL/kg ropivacaine 0.2%), as the control group, and dexmedetomidine (2 µg/kg) and ropivacaine 0.2% (1 mL/kg) in the DR group. The pain score (modified CHEOPS score), duration of analgesia, amount of analgesia consumed (i.v. paracetamol), hemodynamic changes, and possible adverse effects were assessed at one, two, and six hours in both groups.

 The pain score at one and two hours showed no significant difference between the two study groups (P > 0.05). In the DR group, however, the pain score at the sixth hour was significantly lower, and the duration of analgesia was longer (P = 0.001). The amount of analgesic consumption was also lower in the DR group (P = 0.001). However, there was no significant difference in systolic blood pressure and heart rate (P < 0.05), in the case of diastolic blood pressure, a significant difference (P < 0.05) was seen (DR group lower than the R group). There was no statistically significant difference between the study groups in the duration of surgery, recovery time, and side effects (P < 0.05).

 In the present study, the addition of dexmedetomidine to ropivacaine in the caudal epidural blockade improved postoperative analgesia without significant adverse effects in pediatric patients.
