Lateral Sagittal Versus Costoclavicular Approaches for Ultrasound-Guided Infraclavicular Brachial Plexus Block: A Comparison of Block Dynamics Through A Randomized Clinical Trial.

ABSTRACT: Introduction In this study, our objective was to compare the lateral sagittal infraclavicular block (LS-ICB) with the costoclavicular infraclavicular block (CC-ICB) for ultrasound (US)-guided infraclavicular brachial plexus block in terms of block dynamics as well as patient and surgeon satisfaction levels. Methods A total of 100 patients, falling under the American Society of Anaesthesiologists (ASA) I-III categories, who were aged 18-65 years and scheduled for elective forearm and hand surgery were enrolled in the study. The patients were randomly allocated to receive a US-guided LS-ICB or US‑guided CC-ICB. The local anesthetic (LA) agent used (20-ml 0.5% bupivacaine) was identical in all subjects. The block performance time and the motor and sensory block onset times were determined to be the primary outcomes. Results The block performance time and the sensory block onset time were shorter in the CC-ICB group compared to the LS-ICB group [median (interquartile range): three (2.5-3.3) vs. two (1.5-2.3) minutes, p: <0.001; five (4.4-6) vs. four (3.8-6) minutes, p = 0.022, respectively]. The number of needle redirections was lower in the CC-ICB [three (2.7-4) vs. two (one to two) times, p: <0.001]. The motor block onset time and the motor-sensory block times were similar in both groups. There were more patients with a complete sensory blockade at five and 10 minutes in the CC-ICB group than in the LS-ICB group (30% vs. 12%, p = 0.027; 66% vs. 26%, p: <0.001, respectively). No complications were observed with regard to both techniques, and patient and surgeon satisfaction levels observed were similar for both groups. Conclusion Based on our findings, the CC approach provided a shorter performance time and a faster onset of the sensory block compared to the LS approach. However, no complications were reported with respect to either technique, and similar patient and surgeon satisfaction levels were observed.

Project description:We hypothesized that ultrasound (US)-guided technique of the supra- and infraclavicular and axillary approaches of brachial plexus block (BPB) will produce a high quality of surgical anesthesia for operations below the shoulder independently of the approach and body mass index (BMI). Intercostobrachial and medial brachial cutaneous nerves will be blocked separately because they are not a part of the brachial plexus. This is a prospective randomized observer-blinded study. The three approaches of the US-guided BPB without neurostimulation were compared for quality, performance time, and correlation between performance time and BMI. Intercostobrachial and medial brachial cutaneous nerve blocks were used in all patients. A total of 101 patients were randomized into three groups: SCL (supraclavicular), ICL (infraclavicular), and AX (axillary). Seven patients were excluded due to various factors. All three groups were similar in demographic data, M:F proportion, preoperative diagnosis and type of surgery, anesthesiologists who performed the block, and surgical staff that performed the surgical intervention. The time between the end of the block performance and the start of the operation was also similar. The quality of the surgical anesthesia and discomfort during the operation were identical following comparison between groups. No direct positive correlation was observed between BMI and the block performance time. The time for the axillary block was slightly longer than the time for the supra- and infraclavicular approaches, but it had no practical clinical significance. Transient Horner syndrome was observed in three patients in the SCL group. No other adverse effects or complications were observed. All three approaches can be used for US-guided BPB with similar quality of surgical anesthesia for operations of below the shoulder. A block of the intercostobrachial and medial brachial cutaneous nerves is recommended. Obesity is not a significant factor in relation to the time of US-guided BPB performance, or the quality of surgical anesthesia. (ClinicalTrials.gov number, NCT01442558.).
