Coating a single-layer appositional jejunal anastomosis with SCMC or HA solutions does not adversely affect anastomotic healing. Application of 0.4% HA solution to the serosal surface of the jejunum significantly decreases the incidence of experimentally induced intra-abdominal adhesion formation in horses.

Summary This retrospective study was initiated to identify complications of anaesthesia occurring during ocular surgery. Records of 74 horses anaesthetised for eye enucleation, 65 horses anaesthetised for surgery of the eye and adnexa, and 51 horses anaesthetised for splint bone excision were reviewed. Fifty‐three percent of the horses anaesthetised for eye enucleation moved during surgery which was significantly more frequent than in the other groups (P = 0.001). The incidence of moving was significantly reduced by use of an anaesthetic gas analyser for monitoring (P = 0.001). Transient hypertension was measured in 6 horses during removal of the eye. One horse experienced a momentary decrease in heart rate from 36 to 26 beats/min at the start of surgery involving a mass on the third eyelid. The incidence of unsatisfactory recovery from anaesthesia involving multiple attempts to stand was significantly greater after ocular surgery than after splint bone excision (P = 0.036). Our conclusions were 1) the oculocardiac reflex was not active in these horses undergoing ocular surgery, 2) increased attention must be paid to provision of analgesia and adequate depth of anaesthesia, which may be facilitated by use of an anaesthetic gas analyser and 3) horses were at greater risk for unsatisfactory recoveries from anaesthesia after ocular surgery.
