The anesthetic and recovery profiles of low-dose hypobaric mepivacaine and bupivacaine for spinal anesthesia in total hip and knee arthroplasty: a prospective observational study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeSame-day mobilization and early hospital discharge is increasingly emphasized following hip and knee arthroplasty. One challenge of spinal anesthesia in this setting is achieving adequate block height while avoiding excessively large local anesthetic doses and prolonged motor and sensory blockade. Using a hypobaric local anesthetic solution is one potential strategy, as its intrathecal distribution can be reliably manipulated by patient positioning to achieve adequate block height independent of dose.
methodsWe conducted a prospective observational study to determine the clinical characteristics of spinal anesthesia with low-dose hypobaric mepivacaine and bupivacaine in patients undergoing hip and knee arthroplasty. Thirty patients scheduled for same-day discharge received 51 mg of hypobaric 1.5% mepivacaine and 30 patients scheduled for inpatient stay received 10 mg of hypobaric 0.33% bupivacaine.
resultsThe mean (standard deviation) time to achieve sensory blockade at or above L1 and T10 in the operative limb was 5.7 (1.8) and 7.3 (3.3) min with mepivacaine and 6.2 (2.6) and 8.1 (4.8) min with bupivacaine, respectively. Anesthesia was adequate for surgical commencement in all patients regardless of spinal injection level. Four patients required anesthetic supplementation for surgical completion. Sensory block duration at or above T10 and L1 in the operative limb was 97 (27) and 115 (37) min with mepivacaine and 127 (32) and 161 (34) min with bupivacaine, respectively. Motor function returned by 145 (37) and 217 (43) min in mepivacaine and bupivacaine groups, respectively.
conclusionThe anesthetic profiles of low-dose hypobaric mepivacaine and bupivacaine were favorable for fast-track hip and knee arthroplasty with short and predictable operating times.
