Objective To investigate PPH of rectal nerve block anesthesia with the implementation of the anatomical basis and clinical application by verified.Methods Ischioanal fossas of 15 prostrated adult cadaveric specimens(30 s i d e s)were dissected to observe the distance and angle from anal nerves to anus.The adjacent structures of th anal nerves and it’s location point were also be measured.Application the clinical data of the method of location mark the implementation for 51 cases of PPH.Results The length from 3 o’clock or 9 o’clock position at anus to the trunk of anal nerves was about(4.93±0.91)cm(3.80~7.10cm).The angle of declination to the trunk from both positions was(15.6±3.3)°(15~20°).51 cases were operated in accordance with the implementation of the location mark to anal nerve block anesthesia,the patient can tolerate surgery stimulate,no additional intraoperative anesthetic and analgesic drugs,no anesthesia accidents,only 5 cases of urinary retention.Conclusion The position of anal nerves is quite invariable.The trunk of anal nerves locates in the outer 1/3 segment of the line of coccygeal tip to ischial tuberosity and is 2.21cm away from the medial region of ischial tuberosity,it is about 1.36cm in the front of the most bulgy aspect of the ischial tuberosity at the same level.This spot will be a much effective site for block anesthesia and can be implemented for the PPH.
