ABSTRACT
Objective To discuss the epidural cavity surgical anatomical physiology under fiber optic epidural catheter, and to analyze the technological advantages compared to the the agent under blind. Methods 60 cases who need to epidural abdominal surgery from Jan. to Nov. 2013 were collected. Common duct (30 cases) and fiber optical epidural catheter (30 cases) were respectively used at anesthesia, and the epidural cavity surgical anatomy physiology were observed. Results Compared with indexs before anesthesia, before induction and before intubation, the HR, SPB, and MAP in 5 min after intubation and at the moment of skin incision were of statistically significant differ-ences (P<0. 05). There is a cavity between epidural space and vertebral canal periosteum which is not linked to cranial cavity, but there were a certain amount of connective tissue and venous plexus. The volume of the cavity was about 100 mL, the front and side were narrow and the back was wide, and it began to gradually expand from the neck, and reached its peak at the waist, and then gradually narrowed, un-til the sacral hiatus. Conclusion Fiber optic epidural catheter could make the patient’ s anatomy physiology structure more clear, and it also make it possible to cathetering visually for the anesthesiologist.
ABSTRACT
OBJECTIVE:To evaluate the postoperative analgesic effects and side effects of buprenorphine versus ketamine for patients with patient-controlled epidural analgesia(PCEA).METHODS:60 patients withⅠ～Ⅱ grade in physical status evaluated by American society of anesthesiologists(ASA)scheduled for lower abdomen surgery by lumbar anesthesia combined epidural anesthesia were divided into three groups by a randomized double blind method to be treated with Buprenorphine + Droperidol(Group A),Buprenorphine + Droperidol + Bupivacaine(Group B),or Ketamine + Droperidol+ Bupivacaine(Group C).The visual analogous scale(VAS),Ramsay scale,frequency to press the analgesia pump was recorded at 0～48 h after operation,the time spent for the recovery of intestinal functions;score for nausea vomiting and other adverse drug reactions were observed.RESULTS:Frequency to press the analgesia pump,VAS score and Ramsay score in Group A in different period of time were all significantly different from those in Group B and Group C(P
