To study the effectivness of relaxation hypnosis in cataract surgery.
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.
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
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.
