Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Medial approach to costoclavicular block defined by Nieuwveld involves placement of the linear ultrasound probe on the midclavicular line in parallel with the clavicular, as in the lateral approach, followed by imaging of the three cords alongside the axillary artery, whereupon the needle is directed from the medial to the lateral with the in-plane technique and applying local anaesthetic injection to the midpoint of three cords.
The sample size calculation is done based on the time for establishing total anaesthesia and anaesthesia lead time variables in reference to the study conducted by Prangmalee Leurcharusmee et al. Calculating for 16±5 for lateral approach and 21±7 for medial approach, it is calculated that each group should include 44 patients at 80% power and 95% reliability rate for a meaningful difference at 5 minutes, requiring a total of 88 patients.After obtaining approval of the local ethics board, 88 patients who are considered for emergency or elective superior extremity surgery, in ASA I-IV group, in 18 to 75 age group, who do not have any known serious illness and who consent to participate will be included in the study.
Material and Method:Patients in ASA IV group and above, patients taking anticoagulant/antiaggregate treatments, patients with nervous disorders, patients with infections or open wounds at the operation area and patients with allergies against any drug to be used in the study will be excluded from the study.
Patients participating in the study will be randomly divided into 2 separate groups. These groups will be referred to as the Group M (Medial approach group) and Group L (Lateral approach group).
Patients will be reviewed before being taken to operating room, they will be informed regarding the considered operation and their consent will be taken. Patients will be moved to regional anaesthesia room before the operation, where they will be equipped with fingertip oxygen saturation monitoring and 20-22 gauge intravenous channel. After confirming operation area sterilisation will be done with skin antiseptic, the operation area will be covered with sterilised cover and linear USG probe will be prepared in sterile conditions. All procedures will be implemented by an experienced anaesthesiologist. A blind researcher will review the patients and the surgical team will also be kept blind regarding the type of procedure.
In Group M, after the patient will be taken to the regional anaesthesia room and preparations will be made, the blockage procedure will be applied by an anaesthesiologist who is not blind. The patient will be brought to supine position, the arm subject to procedure will be taken to 90° abduction with the palm looking at the ceiling. The Linear USG probe will be positioned on the midclavicular line and the chronometer will be started to record the scanning procedure time as the time elapsed until imaging of the axillary artery alongside with the three cords. After achieving optimum imaging skin infiltration will be applied with 1% lidocaine and an 80-100 mm needle will be directed from the medial to the lateral with the in-plane technique and the blockage procedure will be completed by injecting a combination of 10 cc 2% lidocaine and 10 cc 0.5% bupivacaine in the exact midpoint of the three cords.
In Group L, again the patient will be taken to the regional anaesthesia room and preparations will be made, and the blockage procedure will be applied by an anaesthesiologist who is not blind. The patient will be brought to supine position, the arm subject to procedure will be taken to 90° abduction with the palm looking at the ceiling. The Linear USG probe will be positioned on the midclavicular line and the chronometer will be started to record the scanning procedure time as the time elapsed until imaging of the axillary artery alongside with the three cords. After achieving optimum imaging skin infiltration will be applied with 1% lidocaine and an 80-100 mm needle will be directed from the medial to the lateral with the in-plane technique and the blockage procedure will be completed by injecting a combination of 10 cc 2% lidocaine and 10 cc 0.5% bupivacaine in the exact midpoint of the three cords.
The total procedure time, the complications arising during procedure, the local anaesthetic toxicity, the paraesthesia arising during the procedure, the distance between the needle tip and the pleura and the number of needle passes will be recorded for each procedure. A blind researcher will evaluate sensory blockage by checking radial, musculocutaneous, medial and ulnar nerve dermatomes with ice using triple point scale (0= no blockage, patient completely feels the cold; 1= analgesia, the patient does not feel the cold but feels the touch; 2= anaesthesia, the patient does not feel the touch) once per 5 minutes for 30/45 minutes taking the moment of needle removal as the 0 point. Motor block will also be evaluated by triple point scale (0=no blockage; 1=paraesthesia established; 2=paralysis established) once per 5 minutes for 30 minutes. Motor blockage at musculocutaneous, radial, median and ulnar nerves will be evaluated by elbow flexion, thumb abduction, thumb opposition and thumb adduction, in this order. Sensory and motor blockage starting time points and total anaesthesia establishment time points will be recorded. At 20/30 minutes point convex (M mode) USG probe will be used to evaluate diaphragmatic paralysis. Once surgical anaesthesia is established the operation will be started, the patient will be monitored throughout the operation, additional analgesia-sedation needs, returns to general anaesthesia and total surgery times will be recorded. After surgical operation is completed, patient and surgeon satisfaction will be questioned.
