1 · What the graph read from it

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.

Abstract

BACKGROUND AND

aimsSubcostal transversus abdominis plane (TAP) block is usually done under ultrasound guidance in laparoscopic cholecystectomy. Laparoscopic-guided subcostal TAP block is an alternate technique where ultrasound is not available. Our primary objective was to compare the success rate of ultrasound and laparoscopic approaches to the subcostal TAP block. The secondary objectives were to assess the duration of postoperative analgesia and morphine consumption postoperatively for 24 h.

methodsEighty patients undergoing laparoscopic cholecystectomy were randomly divided into two groups with patients receiving ultrasound-guided (group U) or laparoscopy-guided (group L) subcostal TAP block at the end of surgery. The success rate was assessed by a sensory blockade of T7 and T8 dermatomes 30 min after extubation. The duration of analgesia was taken as time from block administration to the visual analogue scale of ≥3. Morphine was administered in patient-controlled analgesia (PCA) pump with a bolus of 1 mg and a lock-out interval of 10 min. The total morphine consumption was recorded. The statistical analysis was performed with student

resultsThe success rate of group U (100%) was higher than group L (88%) but it was not statistically significant (

conclusionLaparoscopy-guided subcostal TAP block is a suitable alternative to ultrasound-guided block and can be utilised in places where an ultrasound machine is not available.
