Standards of practice for peripheral nerve blocks at a tertiary care center in a low-middle income country- a prospective observational study.
Observational study in BMC anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPeripheral nerve blocks (PNB) have gained tremendous interest as a means of providing anesthesia and analgesia. Heterogeneity exists in the standards of practice (SoP) for PNB, especially in resource limited settings. Therefore, this study aimed to determine the SoP for administration of PNB at a tertiary care, University teaching hospital, in a low-middle income country (LMIC).
methodsThis was a prospective observational study conducted between September 2021 and March 2023. The SoP were collected through either direct or indirect observation, using a self-developed proforma. Data were collected for various domains and were mapped to structure, process and outcome. They were then benchmarked to identify best practices and deficiencies.
resultsA total of 386 PNBs were recorded, of which 196 (50.8%) were directly observed. Majority were administered to low-risk individuals without comorbidities (61.9%). In the structure metrics resuscitation equipment was available in 76% while availability of resuscitation drugs (29%) was identified as needing improvement. Individual components of process metrics such as intravenous access, use of personal protective equipment, ultrasound guided block technique and use of short bevel needles exceeded the 95% benchmark, while components such as monitoring (54%), aseptic site preparation (76.5%), the Stop Before You Block procedure (61.9%) and use of block additives (70.2%) fell short of the benchmark. Postoperative multimodal analgesia prescription (4.7%) was identified as needing improvement. Of the outcome metrics, while immediate post-block complications (0%) and conversion rate to general anesthesia (8.3%) exceeded the benchmark (< 10%), cumulative toxic dose was exceeded (36.6%) when a mixture of local anesthetics was used.
conclusionStandards of practice for structure, process and outcome were partly achieved for PNB at this tertiary care center in a low-middle income country. Strategies to improve SoP have been proposed and will need to be evaluated in future quality improvement initiatives.
