Adverse effects of vapocoolant and topical anesthesia for tail biopsy of preweanling mice.
Article in Journal of the American Association for Laboratory Animal Science : JAALAS, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Tail biopsy of laboratory mice for genotyping purposes has been studied extensively to develop refinements for this common procedure. Our prior work assessed tail vertebral development in different mouse strains (age, 3 to 42 d) and analyzed behavior and activity in mice (age, 21 to 45 d) biopsied under isoflurane anesthesia. To assess the effects of biopsy on preweanling mice, we here evaluated BALB/cAnNCrl mice (n = 80; age, 18 to 21 d) that received topical vapocoolant (ethyl chloride), topical anesthetic (Cetacaine), or isoflurane anesthesia before undergoing a 5-mm or sham biopsy. Control mice did not receive any anesthetic intervention. Regardless of the anesthetic used, acute observation scores indicative of distress were increased at 10 min after biopsy, and locomotor activity was decreased, in biopsied compared with control mice. Acute observation scores at 10 min after biopsy were higher in mice that received ethyl chloride compared with isoflurane or no anesthesia. Microscopic analysis revealed that inflammatory changes in the distal tail remained elevated until 7 d after biopsy and were higher in tails exposed to ethyl chloride. Our findings indicate that vapocoolant, topical anesthesia, and inhaled isoflurane do not enhance the wellbeing of preweanling mice undergoing tail biopsy. Due to the lack of appreciable benefits and the presence of notable adverse effects, using vapocoolants or Cetacaine for this tail biopsy procedure in laboratory mice is unadvisable and we encourage the removal of these agents from institutional tail biopsy guidelines.
