Implication

Observational study compares hemidiaphragmatic paresis incidence in patients receiving different volumes of local anaesthetics during shoulder surgery.

Key Points

To determine the effect of varying volumes of local anaesthetics on the incidence of hemidiaphragmatic paresis after interscalene brachial plexus block.
Conducted a comparison among three groups receiving 10 ml, 15 ml, and 20 ml of local anaesthetic.
Administered 0.75% ropivacaine with dexmedetomidine.
Measured diaphragm excursion and assessed incidence and severity of diaphragmatic palsy.
Evaluated success rate, onset of sensory blockade, duration of analgesia, and adverse effects.
Significant differences in hemidiaphragmatic paresis between groups (p < 0.001).
Group A had the lowest incidence of paresis.
Faster onset of sensory blockade observed in Group C (4.61 min, p < 0.001).
Postoperative analgesia duration was statistically insignificant across groups.
