Abstract
|
|
|
From January, 1976 to April, 1977, we performed caudal anesthesia for 40 cases of hemorrhoidectomy, anal fistulectomy and drainage of perianal abscess at Seoul Red Cross Hospital.
We studied onset-time of, analgesia, time of full analgesia, duration of analgesia, complications and muscle relaxation by using the 1, 5 percent or 2 percent lidocaine solution 15 ml or -20 ml with or without, epinephrine.
The results were as follows;
1) The onset time of analgesia was 2~7 minutes (average 4.2 minutes) after injection of lidocaine solution into the sacral canals.
2) The loss of all sensations was occurred at 5~25 minutes (average 13.7.r minutes) after injection of lidocaine solution into the sacral canals.
3) Muscle relaxation revealed good in 25 cases fair in-14 cases and no inadequate relaxation. was noted.
4) The average duration of analgesia was 83.7 -minutes without epinephrine, 130 minutes with epinephrine.
5) Cardiovascular changes were minimal. The changes of blood pressure and pulse rate were no significant and they could be treated, with vasopressor drugs.
6) Respiration was not affected by caudal anesthesia.
7) No systemic effects of local anesthetics were noted. The safe dosage of local anesthetic could-be prevented systemic toxic reaction of lidocaine.
8) Caudal block was preferred to spinal saddle block for operations on the anus, because the postspinal headache was eliminated unless the dura was. punctured .inadvertently and the Jack -knife position might be used without a high level of anesthesia ensuing.
