The circulation responses of systolic blood pressure, diastolic blood pressure, and pulse rate during implant placement under local anesthesia were analyzed. The subjects were 30 normal healthy patients (ASA-PS-1).
The operational steps were the beginning of local anesthesia, five minutes after the anesthesia, surgical flap procedures, drilling, implant placement, suture, and completion of the surgery. The data of each step were identified based on the Video Overlay Monitoring System (VOLMS) images and printed output from Automated Surgery Recording System (ASURS).
The controls for fluctuation were the preoperative values obtained from the Preoperative Values Searching Program of VOLMS. Every possible effort was made not to give stress to the patient with the help of the advisory marks from VOLMS that indicated fluctuations. As a result, any of the fluctuations was transitory and none of them were serious. At the beginning of local anesthesia and five minutes after that, as well as at the time of drilling, the circulation responses rose significantly in the statistical viewpoint. At the end of the surgery, however, all of the three parameters became almost equal to their respective preoperative values.
