“…The study of different doses of 0.4% enantiomeric excess levobupivacaine (S75:R25) for unilateral orthopedic surgeries reflected in a dose-dependent duration of action. [ 35 ] Low doses of 4, 6 and 8 mg provided recovery times of 75, 117, and 174 min, respectively, with positive correlation between doses. [ 35 ]…”

The injection of a non-isobaric local anesthetic should induce a unilateral spinal anesthesia in patients in a lateral decubitus position. The posterior spinal hemianesthesia only be obtained with hypobaric solutions injected in the jackknife position. The most important factors to be considered when performing a spinal hemianesthesia are: type and gauge of the needle, density of the local anesthetic relative to the CSF, position of the patient, speed of administration of the solution, time of stay in position, and dose/concentration/volume of the anesthetic solution. The distance between the spinal roots on the right-left sides and anterior-posterior is, approximately, 10-15 mm. This distance allows performing unilateral spinal anesthesia or posterior spinal anesthesia. The great advantage of obtaining spinal hemianesthesia is the reduction of cardiovascular changes. Likewise, both the dorsal and unilateral sensory block predominates in relation to the motor block. Because of the numerous advantages of producing spinal hemianesthesia, anesthesiologists should apply this technique more often. This review considers the factors which are relevant, plausible and proven to obtain spinal hemianesthesia.

“…23 This unnecessarily high concentration of 8% has been reported to allow the usage of low dose and additional adjuvants. 9 However, in literature, local anaesthetics containing dextrose at 8% concentration are often used for unilateral spinal anaesthesia. 8,10,24 In the current study, the density of the solution containing 3% concentration dextrose in Group I was measured as 1.008 g L −1 at 37 • C. From the results of the study, it was determined that this difference from CSF in density was sufficient to form a unilateral block.…”

“…9 It has been reported that the best result for unilateral block is achieved with 10---20 min waiting in the lateral decubitus position after using a low dose of local anaesthesia. 25 In the current study, a 10 min waiting period after the procedure was preferred.…”

“…In Group I with the lowest dextrose content, the time to sensory block onset was longer compared to the other groups and the maximum block level was lower than that in Group III. In literature it has been reported that an increase in local anaesthesia solution density has the effect of accelerating onset 6,9,26,27 and causes an increase in maximum block level. 4,27 In the current study, the time to full recovery of both sensory and motor blocks was shorter in Group I.…”
