The effect of bilateral ultrasound-guided erector spinae plane block on postoperative pain control in idiopathic scoliosis patients undergoing posterior spine fusion surgery: study protocol of a randomized controlled trial

BackgroundPosterior spinal fusion (PSF) for the correction of idiopathic scoliosis is associated with severe postoperative pain. Erector spinae plane block (ESPB) has been proposed to provide analgesia and reduce opioid consumption. We aimed to investigate the effect of bilateral ultrasound-guided single-shot ESPB on postoperative analgesia in pediatric patients undergoing PSF.MethodsThis double-blinded, randomized controlled trial will enroll 74 AIS patients undergoing elective PSF. Participants will be assigned to the ESPB group or control group at a 1:1 ratio. Patients in the ESPB group will receive ultrasound-guided bilateral ESPB preoperatively, and patients in the control group received sham ESPB using normal saline. The primary joint endpoints are the area under the curve (AUC) of numerical rating scale (NRS) score and opioid consumption in postoperative 24 h. The secondary endpoints are numerical rating scale (NRS) score and opioid consumption at postoperative 0.5, 3, 6, 9, 12, 24, 36, and 48 h, rescue analgesia, recovery outcomes, and adverse events.DiscussionAt present, studies investigating the effect of ESPB on pediatric patients are still needed. This study focuses on the effect of ESPB on pediatric patients undergoing PSF on postoperative pain control and intends to provide a new strategy of multimodal analgesia management for major spine surgery.Trial registrationChinese Clinical Trial Registry ChiCTR2300074505.

Intraoperative application of low-dose dexmedetomidine or lidocaine for postoperative analgesia in pediatric patients following craniotomy: a randomized double-blind placebo-controlled trial.

Postoperative pain is a common occurrence in pediatric patients following craniotomy, often leading to negative outcomes. Intravenous dexmedetomidine and lidocaine are commonly used adjuvant medicines in general anesthesia to reduce perioperative opioid consumption and relieve postoperative pain in adults. While they show promise for use in pediatrics, the evidence of their application in pediatric craniotomy patients is limited. Therefore, we aimed to compare the effects of dexmedetomidine and lidocaine on postoperative pain in pediatric patients following craniotomy. We conducted a randomized, double-blind, single-center trial on children scheduled for craniotomy. The 255 recruited participants aged 1-12 years were randomly assigned to intraoperatively receive a loading intravenous dose of either dexmedetomidine 1 μg·kg-1 or lidocaine 2 mg·kg-1 or normal saline for 15 min followed by dexmedetomidine 0.5 μg·kg-1·h-1 or lidocaine 1 mg·kg-1·h-1 or normal saline until the sutures of endocranium were completed. The primary outcome was the cumulative sufentanil consumption within 24 h post-surgery. A total of 241 patients were included in the statistical analysis. The primary outcome did not show any significant differences among the three groups (median (IQR) lidocaine group: 3.36 (1.32-5.64) μg vs. dexmedetomidine group: 3.12 (1.36-6.39) μg vs. control group 3.46 (1.77-7.62) μg, p = 0.485). Among the secondary outcomes, there was a statistically significant but small reduction in sufentanil consumption within 2 h, postoperative FLACC/WBFS/NRS pain scores within 4 h after surgery and postoperative Ramsay sedation scores in dexmedetomidine group (p < 0.05). Regarding postoperative complications, the incidence of electrolyte disturbance within 24 and 48 h after surgery was significantly higher in control group compared to the other two groups. There were no significant differences in intraoperative opioid consumption, postoperative frequency of remedy medication, or length of hospitalization among the three groups. No adverse events related to lidocaine or dexmedetomidine were observed. There were no significant differences in the primary outcome among the three groups. Although dexmedetomidine showed some benefits in reducing postoperative opioid consumption within the first 2 h and pain intensity within the first 4 h post-surgery, these findings should be interpreted with caution. Further research is required to comprehensively assess the outcomes and determine the optimal administration strategy. [http://www.chictr.org.cn/index.aspx], identifier [ChiCTR1800019411].

Effect of ultrasound-guided quadratus lumborum block on neuroendocrine stress response and postoperative analgesia in paediatric patients undergoing elective open pyeloplasty - A randomised clinical trial.

Quadratus lumborum block (QLB) is a compartmental block of the anterior abdominal wall. Surgical trauma produces neuroendocrine surgical stress responses, which are modified by anaesthetic blocks. The aim of this study was to evaluate the effect of ultrasound (US)-guided QLB on analgesia and surgical neuroendocrine stress response in paediatric patients undergoing pyeloplasty. A randomised trial was conducted in 60 children aged 1-7 years undergoing elective open pyeloplasty. Patients were randomised into Group QLB [US-guided QLB with 0.5 ml/kg of 0.25% ropivacaine after induction of general anaesthesia (GA)], and Group GA, which received only GA. Perioperative haemodynamic parameters, serum cortisol, blood glucose, analgesic consumption and postoperative FLACC scores were recorded. Unpaired t-test, Wilcoxon rank-sum test or Mann-Whitney U test was used to compare variables between the two groups. Two-way analysis of variance or the Friedmann test was used to compare quantitative variables at various points within a group. A decrease in serum cortisol and blood glucose values was observed in Group QLB at 30 min after surgical incision and 24 h after surgery compared to the preoperative value and compared to Group GA (P < 0.05). The quality of analgesia assessed by the FLACC scale was significantly better in group QLB. Dose of fentanyl consumption (µg/kg) was higher in Group GA compared to Group QLB in the intraoperative and postoperative period (P < 0.05). QLB is effective as part of multimodal analgesia and attenuates the neuroendocrine stress in paediatric patients undergoing open pyeloplasty.

Postoperative Analgetic Profile in Pediatric Patients at Dr. Kariadi Hospital

Background: Pain management is pivotal for pediatric patients post-surgery due to its common occurrence and significant impact on well-being. Effective management involves considerations such as surgical type, analgesic selection, and proper pain assessment.Objective: Knowing the profile of postoperative analgesia in pediatric patients at Dr. Kariadi Hospital using pain assessment instruments based on age classification.Method: Employing an observational descriptive approach with a prospective cohort design, the study sampled 172 pediatric patients across varying pain severity levels. Utilizing total sampling, patients were assessed using age-specific pain instruments. Descriptive statistics were utilized to describe patients' characteristics, as well as the attributes of analgesic effectiveness concerning age, surgery type, and drugs administered. Texts and tables were employed to present the results.Results: Sampling on 172 patients with grouping based on the type of surgery that causes mild, moderate, and severe pain. Pain scales and analgesics were recorded at 4 moments: (1) when entering the recovery room; (2) leaving the recovery room; (3) 8 hours and (4) 24 hours postoperative. The results showed that the highest use of analgesics was paracetamol alone (59.9%); analgesic effectiveness in the mild pain surgery 97.2-98.6%; moderate pain 92.2-98.9%, and severe pain 90.9-100%.Conclusion: Postoperative analgesic utilization in pediatric patients at Dr. Kariadi Hospital is generally adequate, predominantly relying on paracetamol. However, enhancements are needed to optimize pain management, particularly for moderate-to- severe pain cases. Strategies to improve analgesic effectiveness should be pursued to ensure comprehensive pain relief for pediatric surgical patients.

Comparison of Intravenous Dexamethasone along with Caudal Block versus Caudal Block Alone for Postoperative Analgesia in Pediatric Lower Abdominal Surgeries

dexamethasone to a caudal block in enhancing the duration and quality of postoperative analgesia in pediatric patients undergoing lower abdominal surgeries. Methodology: This Randomized Control Trial was carried out Department of Anesthesia, Holy Family Hospital, Rawalpindi from December 2021May 2022. Patients fulfilling inclusion criteria were divided into two groups. Both groups received caudal block with 1 ml/kg of 0.25% Bupivacaine while group A received 0.25 mg/kg of Dexamethasone intravenously as an adjuvant. Post operatively patients were assessed by FLACC scores at different time intervals. All surgeries were conducted under general anesthesia with endotracheal intubation. Either Mapleson F (Jackson Rees Modification of Ayre’s T piece) or circle system used as breathing circuit. Induction of anesthesia using propofol at a dose of 2-2.5 mg/kg along with O2 100% or with sevoflurane 2 to 3% at fresh gas flow of 6 L/minute was carried out. Data was analyzed using SPSS 26.0. Results: Mean duration of analgesia in Group A was 7.77 ± 1.38 hours while it was 5.44 ± 0.91 hours in group B. The difference was statistically significant with a p value of less than 0.05 on Mann Whitney U test. Conclusion: Addition of intravenous dexamethasone to caudal block significantly enhances the duration and quality of analgesia among pediatric patients undergoing lower abdominal surgeries.

Erector spinae plane block versus caudal block for postoperative analgesia in pediatric patients undergoing inguinal hernia repair: a randomized controlled trial

Background Erector spinae plane block is a promising strategy for pain management in some settings. However, the effectiveness of erector spinae plane block versus caudal block in pediatric inguinal hernia repair has yet to be formally investigated. Methods One hundred and two patients aged 2–5 years undergoing unilateral open inguinal hernia repair randomly received unilateral erector spinae plane block (0.2% ropivacaine 0.5 mL kg−1), caudal block (0.2% ropivacaine 1 mL kg−1), or no block. The primary outcome was time to the first rescue analgesia, defined as the interval from the end of surgery to the Face, Legs, Activity, Cry, and Consolability scale greater than three. Secondary outcomes included the number of patients requiring rescue analgesia, the area under the curve of pain scores over time, satisfaction of guardians, and adverse events. Results The median time to the first rescue analgesia was longer in the erector spinae plane block group than in the caudal block group [10.0 h (interquartile range, 6.6–24.0 h) vs. 5.0 h (interquartile range, 2.9–7.3 h); p < .001]. The Cox regression model demonstrated that the risk of postoperative rescue analgesia requirement was 0.38 in children receiving erector spinae plane block compared with caudal block (95% confidence interval 0.23–0.64; p < .001). Additionally, the area under the curve of the pain scores over time was lower in the erector spinae plane block group than in the caudal block group (44.3 [36.6–50.7] vs. 59.0 [47.1–64.5]; p < .001). Conclusions Erector spinae plane block provided superior postoperative analgesia compared to caudal block in children undergoing inguinal hernia repair.

Ultrasound Guided Quadratus Lumborum Block Compared to Caudal Bupivacaine/Neostigmine in Pediatric Lower Abdominal Surgeries: A Randomized Controlled Trial

Abstract Background The postoperative analgesia in pediatric patients undergoing lower abdominal surgeries could be achieved by Quadratus lumborum block (QLB) or Caudal block (CB). The combination of neostigmine and bupivacaine shortens the onset and increases the duration of regional blocks. Methods 80 pediatric patients undergoing lower abdominal surgeries under general anesthesia were randomized to receive either QLB using bupivacaine or CB using bupivacaine/neostigmine mixture. Time to first needed rescue analgesia was considered as a primary outcome while pain score, blood glucose level, nausea, vomiting, bradycardia, hypotension and urinary pretension were considered as secondary outcomes. Results The time to first rescue of analgesia was significantly longer in QLB group (p=˂ 0.001) and rate of rescue analgesia requirements was significantly lower in quadratus lumborum group (p=˂ 0.001), while time to perform the block and block failure were significantly higher in QLB group. Side effects were infrequent and non-significant among groups. Conclusion Postoperative analgesia for pediatric patients undergoing lower abdominal surgeries could be safely and effectively achieved by Quadratus lumborum block and caudal bupivacaine/neostigmine mixture block with priority to caudal block.

Evaluation of USG-guided novel sacral erector spinae block for postoperative analgesia in pediatric patients undergoing hypospadias repair: A randomized controlled trial.

Erector spinae plane block (ESPB) has been found to be simple, safe, and effective at thoracic and lumbar levels. There is no randomized controlled trial evaluating its effectiveness at sacral level. The present study was conducted to evaluate its effectiveness at sacral level for postoperative analgesia in pediatric patients undergoing hypospadias repair. Forty children of 2-7 years with ASA grade I or II were included. They were randomly allocated to one of the two groups of 20 patients each. After induction of general anesthesia, patients of group I were given ultrasound-guided sacral ESPB with 1 ml/kg of 0.25% bupivacaine, and patients of group II were not given block. Postoperatively, pain was assessed using face, legs, activity, cry, consolability (FLACC) scale at 0 hour, every 15 min up to 1 hour, every half an hour up to 2 hours, 2 hourly up to 12 hours, and at 18th hour and 24th hour postoperatively. At FLACC score ≥4, rescue analgesia was given using 15 mg/kg paracetamol infusion. Primary objective was to compare postoperative analgesic (paracetamol) consumption, and secondary objective was time to first rescue analgesia. Mean postoperative paracetamol consumption was 360 ± 156.60 mg in group I and 997.50 ± 310.87 mg in group II (P = 0.001). Time to first rescue analgesia was 906 ± 224.51 min in group I and 205.00 ± 254.92 min in group II (P = 0.001). Sacral ESPB has been found to be effective in reducing postoperative analgesic consumption in pediatric patients undergoing hypospadias repair.

Safety and efficacy of esketamine for postoperative analgesia in pediatric patients with hypospadias.

To explore the safety and efficacy of the combination of continuous intravenous infusion of esketamine with sacral block for postoperative analgesia in pediatric patients undergoing surgery for hypospadias. Pediatric patients (n = 77) undergoing surgery for hypospadias were randomized into two groups: a hydromorphone group (H group, initial dose, 0.02 mg/kg; maintenance dose, 0.01 mg/kg/h) or an esketamine group (E group, initial dose, 0.3 mg/kg; maintenance dose 0.15 mg/kg/h). Caudal epidural block involved injection of 0.2% ropivacaine 1 ml/kg through the sacral hiatus. Age, weight, grade of hypospadias, intraoperative blood loss, operative time, and awaking time of patients were recorded. The Face, Legs, Activity, Cry and Consolability (FLACC) scale and Ramsay sedation scores were recorded when leaving the PACU (0 h) and at postoperative 2, 6, 12, 24, 36, and 48 h. The Pediatric Anesthesia Emergence Delirium Scale (PAED), incidence of hypotension, respiratory depression, nausea and vomiting and pruritus, and the time to first bowel movement after surgery were recorded. There were no significant differences in demographic and clinical characteristics between the H group and the E group. There were no significant differences in FLACC scores at postoperative 0, 2, 6, 12, 24, 36, and 48 h in intra-group and inter-group comparisons. There were no significant differences in Ramsay sedation scores at postoperative 0, 2, 6, 12, 24, 36, and 48 h in the intra-group comparisons. Ramsay sedation scores were significantly lower at postoperative 2, 12, and 36 h in the H group compared to the E group. There were no significant differences in the PAED scale or incidence of nausea and vomiting or pruritus between the H group and the E group. The incidence of hypotension and respiratory depression was significantly lower, and the time to first bowel movement was significantly shorter in the E group compared to the H group. Urinary tryptophan, 5-hydroxytryptamine and substance P levels were significantly lower but arginine was significantly higher in the E group compared to the H group. The combination of continuous intravenous infusion of esketamine with sacral block provided safe and effective postoperative analgesia for pediatric patients undergoing surgery for hypospadias.

Comparison of duration of Postoperative Analgesia after Caudal Block with or without Intravenous Dexamethasone in Paediatric Day Care Infraumbilical Surgeries under General Anaesthesia

Background: Pain is defined as a subject’s conscious perception of modulated nociceptive impulses that generate an unpleasant experience associated with actual or potential tissue damage. General anaesthesia, when combined with regional anaesthesia provides effective perioperative analgesia. Aim of the study was to study the effect of intravenous dexamethasone on duration of post-operative analgesia when given along with intra operative caudal block in paediatric day care infra umbilical surgeries under general anesthesia.&#x0D; Methods: Sixty paediatric patients, American Society of Anesthesiologist’s class I and II, patients were randomly divided in to two groups. In Group D - 30 paediatric patients who were given intravenous dexamethasone in a dose of 0.2 mg/kg iv in 5 ml normal saline along with caudal block with 0.75ml/kg of 0.25% bupivacaine. Group S - 30 paediatric patients who were given 5 ml of normal saline intravenously along with caudal block with 0.75ml/kg of 0.25% bupivacaine. Primary objective of the study was to determine the duration of post-operative analgesia.&#x0D; Results: The demographic data were comparable in both groups. There were no significant difference of mean (SD) Heart Rate and Mean arterial pressure (mmHg) at baseline, post-operative 1st hour, post-operative 2nd hour, post-operative 3rd hour, post-operative 4th hour (p value &gt;0.05). Time for rescue analgesia (minutes) to be given was more in group D when compared to group S (190.67 ± 41.76 versus 181.17± 37.97) however it was not statistically significant. Total duration of analgesia(minutes), i.e., including both intra-operative and post-operative period was more in group D when compared to group S (266.83 ± 37.69 versus 255.73 ± 42.83). However, there was no significant difference between them. (p value=0.188).&#x0D; Conclusion: We conclude that a single bolus dose of intravenous dexamethasone (0.2 mg/kg) given along with caudal block with 0.75 ml/kg of 0.25% bupivacaine did not prolong the duration of postoperative analgesia in paediatric patients.

Analgesic efficacy of ultrasound guided quadratus lumborum block versus ilioinguinal/iliohypogastric nerve block following pediatric open inguinal hernia repair: A prospective randomized controlled trial.

Inguinal hernia repair is a common surgical procedure. We compared the analgesic efficacy of ultrasound-guided anterior quadratus lumborum (QL) block versus ilioinguinal/iliohypogastric (II/IH) nerve block in pediatric patients undergoing open inguinal hernia repair. It was a prospective randomized study in which 90 patients of 1-8 years of age were randomly assigned into control (general anesthesia only), QL block, and II/IH nerve block groups. Children's Hospital Eastern Ontario Pain Scale (CHEOPS), perioperative analgesic consumptions, and time to first analgesic request were recorded. The normally distributed quantitative parameters were analyzed by one-way ANOVA with post-hoc Tukey's HSD test while parameters that did not follow a normal distribution and the CHEOPS score were analyzed using the Kruskal-Wallis test followed by the Mann-Whitney U test with Bonferonni correction for post-hoc analysis. In the 1st 6h postoperative, the median (IQR) CHEOPS score was higher in the control group than II/IH group (P = 0.000) and QL group (P = 0.000) while comparable between the latter two groups. CHEOPS scores were significantly lower in the QL block group than the control group and II/IH nerve block group at 12 and 18h. The intraoperative fentanyl and postoperative paracetamol consumptions in the control group were higher than II/IH and QL groups while lower in QL than II/IH group. Ultrasound-guided QL and II/IH nerve blocks provided effective postoperative analgesia in pediatric patients undergoing inguinal hernia repair with lower pain scores and less perioperative analgesic consumptions in the QL block group compared to II/IH group.

Bilateral erector spinae plane block vs quadratus lumborum block for pediatric postoperative pain management after laparoscopic abdominal surgery: a double blinded randomized study

Background: Postoperative pain management in children can be effectively controlled using regional analgesic techniques. In general, neuraxial blocks pose a higher risk of adverse effects and complications in comparison to peripheral nerve blocks. Recently, both quadratus lumborum block (QLB) and erector spinae plan block (ESPB) have been used to achieve adequate postoperative analgesia in children. We compared the efficacy of both in postoperative pain management after laparoscopic abdominal surgery.&#x0D; Methodology: Eight five patients with laparoscopic abdominal surgery received either bilateral QLB or ESPB at the level of T8 transverse process with 0.5 ml/kg of 0.25% bupivacaine to achieve adequate postoperative analgesia. FLACC score was used to assess pain score after surgery and the need for rescue opioid analgesia.&#x0D; Results: The average dose of fentanyl was lower and the time to the first dose of rescue analgesic was longer in QLB group when compared to ESPB group. In addition, FLACC scores were significantly lower in QLB group in comparison to ESPB group at the 6th, 8th, 12th and 20th h after surgery.&#x0D; Conclusion: Quadratus lumborum block can provide longer and more effective postoperative analgesia in pediatric patients following laparoscopic abdominal surgery in comparison to erector spinae plan block.&#x0D; Citation: Taman HI, Saber HIES, Farid AM, Elawady MM.

Can ultrasound-guided erector spinae plane block replace thoracic epidural analgesia for postoperative analgesia in pediatric patients undergoing thoracotomy? A prospective randomized controlled trial.

Many analgesic modalities have been investigated in pediatrics for thoracotomy. We studied the analgesic efficacy of unilateral continuous ultrasound-guided erector spinae plane block (ESPB) compared to a thoracic epidural in pediatric patients undergoing thoracotomy. A prospective, randomized, observer-blinded, controlled study. Pediatric patients (2-7 years) scheduled for right or left thoracotomy under general anesthesia (GA) were enrolled in the study. We randomly assigned patients into two groups: The thoracic epidural analgesia (TEA) group received GA with an epidural catheter. The ESPB group received GA with a unilateral ultrasound-guided erector spinae plane catheter. The primary outcome was postoperative cumulative opioid consumption for 24 h. The total intraoperative fentanyl requirement was 35.4 ± 11.44 μg in the TEA group and 30.4 ± 9.08 μg in the ESPB group (t-value - 1.53013, P value: 0.134). The total postoperative fentanyl requirement was comparable in both the groups and clinically nonsignificant (44 ± 2.82 in the TEA group vs. 44.25 ± 13.72 in the ESPB group, t-value = -0.02412, P = 0.981). The median (IQR) Face, Legs, Activity, Cry, and Consolability (FLACC) score at 0, 2, 4, 8, 12, and 24 h time points in the ESPB was equivalent to the TEA group. At 6 h time point, the TEA group had a significantly lower FLACC score than the ESPB group (1[1.75, 1] in the TEA group and 2 [2, 1] in the ESPB group, P value = .02, U = 117.5, z-score = -2.218). The complications were higher in the TEA group (urine retention 20% and hypotension 40%) than in the ESPB group (0 and 0%). This study shows that the ESPB provides similar postoperative analgesia to the TEA in pediatric patients undergoing thoracotomy. The ESPB is simpler, faster, and has a lower complication rate.

Ultrasound-Guided Pudendal Nerve Block versus Ultrasound-Guided Dorsal Penile Nerve Block for Pediatric Distal Hypospadias Surgery

Introduction: The primary aim of the study was to use the duration until the first postoperative analgesic requirement after two different block techniques to compare the analgesic effect. The secondary aims were to compare the two methods for postoperative Children’s Hospital Eastern Ontario Pain Scale (CHEOPS) scores, complications, and parental satisfaction level. Materials and Methods: This prospective, observational study was conducted with male patients aged 1–7 years in the ASA I–II group, who were scheduled for hypospadias surgery between November 2019 and April 2020. Ultrasound (US)-guided pudendal nerve block (PNB) or US-guided dorsal penile nerve block (DPNB) was administered under general anesthesia before the operation. Postoperative analgesic need, postoperative pain, complications, and parental satisfaction were noted. The STROBE checklist was followed for reporting. Results: The study was conducted with 30 patients in total, divided into 15 patients receiving PNB and 15 patients receiving DPNB. The effective minimum block duration was longer in the pudendal group at 22.22 ± 0.61 h than in the DPNB group at 22.19 ± 0.57 h. Additional analgesic was required in 4 subjects in the pudendal group and 5 in the DPNB group. There was no statistically significant difference in terms of the variables between the two groups (p > 0.05). Discussion: US-guided DPNB and PNB were shown to provide successful postoperative analgesia and to have similar effectiveness in pediatric patients undergoing hypospadias surgery in this first prospective study of its kind in the literature. Conclusions: US-guided DPNB and PNB have been demonstrated to provide effective, safe, and long-term postoperative analgesia in pediatric patients who have undergone hypospadias surgery. Parental satisfaction in both groups is positively influenced by the minimum postoperative analgesia requirement, the long-term analgesic effect, and the lack of any complications.

Safety and Efficacy of Intrathecal Morphine in Children Undergoing Surgery for Abdominal Neuroblastoma. Dose Finding, Randomized, Clinical Study

Background: Pediatric patients have remained undertreated for postoperative pain because of the difficulty of pain assessment and apprehension. Intrathecal opioids—including morphine—have become a popular method for providing post-operative analgesia in children. Objectives: To compare different doses of morphine via intrathecal route (2 μg/kg, 5 μg/kg, and 10 μg/kg) for post-operative analgesia in pediatric patients following for abdominal neuroblastoma surgery. Methods: This randomized, double-blinded, study was approved by local ethics committee of South Egypt Cancer Institute, Assiut University, Assiut—Egypt, and registered at https://www.clinicaltrials.gov/ at no.: “NCT03158584”. Forty-five patients scheduled for surgical excision of abdominal neuroblastoma were divided into 3 groups (15 patients each); group (I): received intrathecal morphine 2 μg/kg added to normal saline (3 mL volume). Group (II): received intrathecal morphine 5 μg/kg. Group (III): received intrathecal morphine 10 μg/kg. Intra-, and post-operative hemodynamics, FLACC score, time to first request of rescue analgesia, total analgesic consumption, and side effects were recorded for 24 hours. Results: there was a significant reduction in FLACC score in groups II and III starting immediately till 24 hours postoperatively compared to group I (P 0.05). No significant difference was observed between groups in side effects. Conclusions: 5 μg/kg of IT morphine achieved a reasonable balance between postoperative analgesia, and the incidence of side effects in pediatric patients following major abdominal cancer surgeries.

Dexmedetomidine vs. lidocaine for postoperative analgesia in pediatric patients undergoing craniotomy: a protocol for a prospective, randomized, double-blinded, placebo-controlled trial

BackgroundPostoperative pain is a common problem that occurs in pediatric patients following neurosurgery which may lead to severe complications. Dexmedetomidine is a commonly used adjuvant medicine in craniotomy owing to its sedative, amnestic, analgesic, and neuroprotective properties. Besides, studies suggest that lidocaine has similar effects on sedation, analgesia, and neuroprotection. Both two adjuvants can reduce postoperative pain after neurosurgery in adults. However, it is still unknown whether dexmedetomidine or lidocaine can reduce postoperative pain in children undergoing craniotomy, and if yes, which is a better medicine choice. Therefore, we aimed to compare the effect of dexmedetomidine vs. lidocaine on postoperative pain in pediatric patients after craniotomy.Methods/designWe will perform a randomized (1:1:1), double-blind, placebo-controlled, single-center trial. Children aged 1–12 years scheduled for craniotomy will be eligible for inclusion. The 255 recruited participants will be stratified by age in two strata (1–6 years and 7–12 years), and then each stratum will be equally randomized to three groups: group D (infusion of dexmedetomidine [intervention group]), group L (infusion of lidocaine [intervention group]), and group C (infusion of normal saline [control group]). Patients will be followed up at 1 h, 2 h, 4 h, 24 h, and 48 h after surgery. The primary outcome will be total sufentanil consumption within 24 h after surgery.DiscussionIn this clinical trial, we expect to clarify and compare the postoperative analgesic effect of dexmedetomidine vs. lidocaine infusion on pediatric patients undergoing craniotomy. We believe that the results of this trial will provide more choices for postoperative analgesia for the pediatric population.Trial registrationChinese ClinicalTrials.gov ChiCTR1800019411.

Effects of 5 µg/kg intrathecal morphine for postoperative analgesia in pediatric patients undergoing major surgery.

The effects and analgesic adequacy of intrathecal morphine (ITM) administration have been studied less frequently than other regional analgesia techniques in pediatric surgical procedures. To evaluate the efficacy and adverse event rate of 5 µg/kg ITM administration for postoperative analgesia according to age group. We retrospectively evaluated the medical records of patients who underwent major pediatric surgery and were administered ITM for postoperative analgesia. Patients were divided into three age groups: ≤ 5years (group I), 5.1-13years (group II) and > 13years (group III). All patients received ITM 5 µg/kg (max 300 μg) through the L4-5 or L5-S1 interspace. Postoperative pain (modified pediatric objective pain score > 4), need for rescue analgesics, sleep interruption due to pain, sedation (Ramsay sedation scale score > 3), opioid-related postoperative adverse events (at 0, 4, 8, 12, and 24 h after intervention), hemodynamic data and nurse satisfaction with the analgesic method were compared between groups. The analysis included 100children (47girls, 9 ± 5.4years). Groups were similar regarding postoperative rescue analgesia consumption and sleep interruption (p = 0.238, p = 0.958), 96% of the children did not require rescue analgesia, and sleep interruption was not observed in 97%. Postoperative adverse events were pruritus in 14 and nausea/vomiting in 9 patients (p = 0.052). Overall, nurses were satisfied or very satisfied in 99% of the cases. Administration of 5 µg/kg ITM can be used for postoperative analgesia in pediatric surgery in all age groups, with no severe adverse events and high nurse satisfaction with analgesic management.
