Supraclavicular Brachial Plexus Block: Comparison of Varying Doses of Butorphanol Combined with Levobupivacaine - A Double-Blind Prospective Randomized Trial.
Article in Anesthesia, essays and researches. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe ideal dose of butorphanol for brachial plexus block is not well known.
aimsThis study was carried out to evaluate 1 mg and 2 mg of butorphanol added to 0.375% levobupivacaine, with regard to the duration of analgesia. Our study also sought to assess the onset and duration of sensorimotor blockade, hemodynamic effects, sedation, and adverse effects. SETTINGS AND
designThis study was a prospective, randomized, double-blinded, and comparative study.
methodsEighty adult patients of either sex undergoing upper limb surgeries under supraclavicular brachial plexus block were randomly allocated into two groups. Group LB1 received 29 ml of 0.375% levobupivacaine plus 1 mg of butorphanol diluted in 1 ml of normal saline. Group LB2 received 29 ml of 0.375% levobupivacaine plus 2 mg of butorphanol diluted in 1 ml of normal saline. The onset and duration of sensorimotor blockade, level of sedation, duration of analgesia, and adverse effects were assessed. STATISTICAL ANALYSIS: The data were analyzed with Student's
resultsThe onset of sensory (
conclusionHigher dose of butorphanol in brachial plexus block hastens the onset and prolongs the duration of sensorimotor blockade and analgesia but is associated with a higher incidence of sedation which requires intense monitoring.
