Effect of Acupuncture on Hemodynamics and Pain of Post Craniotomy Patients With Mechanical Ventilation

The aim of this clinical trial is to prove that acupuncture therapy combined with standard therapy can optimize hemodynamics and reduce pain in post-craniotomy patients with mechanical ventilation. The main questions it aims to answer are: * Is there a difference in mean arterial pressure, pulse rate, respiratory rate, oxygen fraction and pain in the acupuncture therapy group combined with standard therapy compared to standard therapy after the 3rd therapy and compared to before therapy? * Is there a difference in changes in ventilator mode in the acupuncture therapy group combined with standard therapy compared to standard therapy after the 3rd therapy? * Are there any side effects in the acupuncture therapy group combined with standard therapy? Researchers will compare acupuncture therapy combined with standard therapy to standard therapy only Participants will: * receive acupuncture therapy for 3 consecutive days * outcomes will be assessed after 3 days of therapy.
