Abstract
Purpose:
To study the effectivness of relaxation hypnosis in cataract surgery.
Methods:
Prospective study of 99 patients (104 procedures) who operated under hypnosis ,realized by the same nurse anesthetist. The patients were operated by 2 senior surgeons A and B (A = 54 surgeries, and B = 50 surgeries) under topical anesthesia and 2.2 mm mini-incision. Hypnosis group was comparated to a control group (n=50) according to quantitative and objective criteria: hemodynamic changes (heart rate and blood pressure) and the need for intravenous medication in operating room. Subjective qualitative criteria were surgical comfort, effectiveness of hypnosis and scoring on a scale of 10 patient satisfaction. Analysis by operator subgroup , 1st and 2nd eye surgery are performed.
Results:
The difference for maximum peroperative systolic blood pressure wasn’t significant between the 2 groups (156mmHg + / 2 versus 145 + / -1.4, NS) or maximum heart rate (71 bpm versus 69.6, NS ), However the use of intraoperative intravenous medication was significantly higher in the control group (52% versus 21%, p <0.001). The effectiveness of relaxation is scored at 5.25 / 6 average with only 1.9% of total failure and 6.8% of relative failure. The average patient rating ranged from 9/10 among the hypnosis group, with better cognitive status at their discharge from hospital
Conclusions:
Preliminary results of this study are very positive for the three parts: patient / anesthetist / surgeon. They lead to a pedagogical program of academic training for paramedical personal in the operating room in order to improve the quality of care, reduct the premedication and facilitate their return home.
