Background and Rationale: Ultrasound-guided regional anaesthesia provides superior peri-operative analgesia and reduces opioid use in paediatric upper-limb surgeries. The supraclavicular brachial plexus block (SCB), though widely practiced, carries risks such as pneumothorax and phrenic nerve palsy. The costoclavicular brachial plexus block (CCB), a novel infraclavicular approach, offers potential advantages of safety, faster performance, and reliable spread of local anaesthetic due to the compact arrangement of cords. However, evidence in the paediatric population remains limited, warranting comparative evaluation.
Research Question: Is the ultrasound-guided costoclavicular block comparable to the supraclavicular block in terms of performance time in paediatric patients undergoing upper-limb surgery?
Hypothesis: The ultrasound-guided costoclavicular block is comparable to the supraclavicular block regarding block performance time.
Aim: To compare the costoclavicular and supraclavicular approaches of brachial plexus block with respect to block performance in paediatric upper-limb surgeries.
Objectives: Primary: Compare the performance time between costoclavicular and supraclavicular blocks.
Secondary:
Assess block success rate.
Compare postoperative pain using the CHEOPS score at 2, 4, 6, and 24 hours.
Evaluate diaphragmatic excursion pre- and post-operatively.
Record time to first rescue analgesia.
Study Design: Type: Prospective, randomized interventional study
Setting: Department of Anaesthesia and Intensive Care, VMMC & Safdarjung Hospital, New Delhi
Duration: 18 months
Sample Size: 84 children (42 per group), calculated with 80% power and 5% significance level (based on Guzel et al., 2023).
Methodology: Children aged 1–8 years, ASA physical status I–II, undergoing elective upper-limb surgery will be enrolled after parental consent and ethical clearance. Participants will be randomized using sealed opaque envelopes into two groups:
Group SCB: Supraclavicular approach
Group CCB: Costoclavicular approach
Blocks will be performed under ultrasound guidance following general anaesthesia, using 0.5% Ropivacaine (0.5 mL/kg). Imaging time, needling time, and total procedure time will be recorded. Pain will be assessed using CHEOPS, procedural ease and needle visibility by Likert scales, and diaphragmatic excursion by M-mode ultrasound.
Outcome Measures: Parameter Assessment Tool / Unit Performance Time Stopwatch (seconds) Block Success Rate % requiring rescue analgesia Post-operative Pain CHEOPS Score (4–13) Diaphragmatic Excursion M-mode ultrasound Procedural Ease 3- & 5-point Likert Scales Statistical Analysis: Data will be analysed using SPSS. Continuous variables will be expressed as mean ± SD and compared using t-test/ANOVA; categorical data using Chi-square/Fisher’s exact test. Correlation between variables will be analysed using Pearson/Spearman tests. Statistical significance will be set at p < 0.05.
Ethical Considerations: The study will adhere to ICMR ethical guidelines. Institutional Ethics Committee approval and CTRI registration will be obtained. No additional financial or procedural burden will be placed on participants. Parental information sheets and informed consent forms are included in English and Hindi.
Summary: This study aims to determine whether the costoclavicular block, a newer ultrasound-guided technique, provides a faster, safer, and equally effective alternative to the traditional supraclavicular block for providing peri-operative analgesia in paediatric upper-limb surgeries. |
