Effect of Scalp Nerve Block on the Recovery Quality of Parkinson's Patients After Deep Brain Stimulation

Participants randomized to the SNB group will receive general anesthesia combined with scalp nerve block and intercostal nerve block with 0.5% ropivacaine, which was performed exclusively by an attending anesthesiologist.An attending anesthesiologist will select the site of SNB based on the surgical incision site. Scalp nerve was blocked including greater occipital nerve (2-3ml), superficial temporal nerve (2-3ml), trochlear nerve (2-3ml) and supraorbital nerve (2-3ml). The total volume in scalp nerve block will not exceed 10 ml.Ultrasound-guided unilateral ICNB will be performed at the level of T4-T5 next to the sternum.10-15ml of 0.5% ropivacaine will be injected into the intercostal spaces where incision locates after negative aspiration.
