Abstract

Feasibility and neurologic complications accompanying spinal anesthesia with variable specific gravities were examined in 56 lumbar disc operation from March 1977 to October 1978. Patients' age ranged from 21 to 36 years with 54 cases of males and 2 females. On myelography, lateral and partial blocks were observed in 50 cases and total blocks in 6 cases. These cases were classified depending on the specific gravity and local anesthetics as follows: .Isobaric group: a) 1% tetracain solution, ampule, mixed with C.S.F., 20 cases. b) tetracaine powder with C.S.F., 11 cases. c) 10% procaine solution with C.S.F., 9 cases. .Hyperbaric group: 1% tetracaine solution with 10% dextrose in water, 10 cases. . Hypobaric group: tetracaine powder with water, 6 cases. Under isobaric, hyperbaric and hypobaric spinal anesthesia, good to excellent results were obtained in 90, 90 and 16.6% respectively. More than 10% of systolic blood pressure fall after block was seen in 15, 90 and 16.6% respectively. No neurologic sequalae were observed. Isobaric spinal anesthesia with tetracaine solution is indicated as safer for recently herniated lumbar disc operations.
