AbstractEgyptian fruit bats are experimental animals of increasing interest because they have been identified as a natural reservoir for several emerging zoonotic viruses. For this reason, bats could undergo different experimental procedures that require sedation or anaesthesia. Our aim was to compare the effects of two balanced anaesthetic protocols on sedation, cardiopulmonary variables and recovery in bats undergoing gonadectomy. Twenty bats were randomized into two groups; patients in group DK received intramuscular injection of dexmedetomidine (40 μg kg-1) and ketamine (7 mg kg-1), whereas those in group DBM were anaesthetized with intramuscular dexmedetomidine (40 μg kg-1), butorphanol (0.3 mg kg-1) and midazolam (0.3 mg kg-1). Time of induction, cardiopulmonary parameters and anaesthetic depth were measured. If anaesthesia plan was considered inadequate, fraction of inspired isoflurane was titrate-to-effect to achieve immobility. At the end of the surgery venous blood gas analysis was performed and intramuscular atipamezole (200 μg kg-1) or atipamezole (200 μg kg-1) and flumazenil (0.03 mg kg-1) was administered for timed and scored recovery phase. A significantly higher heart rate and peripheral oxygen saturation were recorded in DBM group (p = 0.001; p = 0.003 respectively), while respiratory rate was significantly lower than DK group (p = 0.001). All bats required isoflurane supplementation during surgery with no significant difference. No differences were observed in rectal temperature, induction and recovery times. Sodium and chlorine where significantly higher in DBM group (p = 0.001; p = 0.002 respectively). Recovery scores in group DK were significantly better than in group DBM (p = 0.034). Both protocols induced anaesthesia in Egyptian fruit bats with comparable sedative and cardiorespiratory effect. These drug combinations may be useful for minor procedures in bats, and they could be associated with inhalation anaesthesia in determining and maintaining a surgical anaesthetic plan.

Background A micro-arteriovenous fistula (AVF) is a minute, short shunt between an artery and a vein that does not pass through a capillary. We investigated the association between micro-AVFs and lymphedema using computed tomography angiography (CTA) and venous blood gas analysis.<br/>Methods In 95 patients with lower limb lymphedema, the presence or absence of early venous return (EVR) was compared between patients with primary and secondary lymphedema. Furthermore, we investigated the difference in the timing of edema onset in patients with secondary lymphedema with or without EVR using CTA. In 20 patients with lower limb lymphedema with confirmed early EVR in a unilateral lower limb, the partial pressure of oxygen (PO2) was compared between the lower limb with EVR and the contralateral lower limb.<br/>Results Secondary lymphedema with or without EVR occurred at an average of 36.0±59.3 months and 93.5±136.1 months, respectively; however, no significant difference was noted. PO2 was 57.6±11.7 mmHg and 44.1±16.4 mmHg in the EVR and non-EVR limbs, respectively, which was a significant difference (P=0.005).<br/>Conclusions EVR and venous blood gas analysis suggested the presence of micro-AVFs in patients with lower extremity edema. Further research is warranted to examine the cause of micro-AVFs, to advance technology to facilitate the confirmation of micro-AVFs by angiography, and to improve lymphedema by ligation of micro-AVFs.

IntroductionVenous sampling for blood gas analysis has been suggested as an alternative to arterial sampling in order to reduce pain. The main objective was to compare pain induced by venous and arterial sampling and to assess whether the type of sampling would affect clinical management or not.MethodsWe performed an open-label randomised multicentre prospective study in four French EDs during a 4-week period. Non-hypoxaemic adults, whose medical management required blood gas analysis, were randomly allocated using a computer-generated randomisation list stratified by centres with an allocation ratio of 1:1 using random blocks to one of the two arms: venous or arterial sampling. The primary outcome was the maximal pain during sampling, using the visual analogue scale. Secondary outcomes pertained to ease of sampling as rated by the nurse drawing the blood, and physician satisfaction regarding usefulness of biochemical data.Results113 patients were included: 55 in the arterial and 58 in the venous sampling group. The mean maximal pain was 40.5 mm±24.9 mm and 22.6 mm±20.2 mm in the arterial group and the venous group, respectively, accounting for a mean difference of 17.9 mm (95% CI 9.6 to 26.3) (p<0.0001). Ease of blood sampling was greater in the venous group as compared with the arterial group (p=0.02). The usefulness of the results, evaluated by the prescriber, did not significantly differ (p=0.25).ConclusionsVenous blood gas is less painful for patients than ABG in non-hypoxaemic patients. Venous blood gas should replace ABG in this setting.Trial registration numberNCT03784664.
