✦ Synopsis
This prospective, controlled study was conducted to compare the effects of tracheal intubation and extubation on intra‐ocular pressure changes and haemodynamic parameters in paediatric patients with and without glaucoma. The children were scheduled for intra‐ocular surgery. Twenty children with normal intra‐ocular pressure and 15 with glaucoma were studied. A standardised general anaesthetic was administered to both groups. After 5 min of anaesthesia, intra‐ocular pressure, heart rate and noninvasive blood pressure were measured. These measurements were repeated 30 s and 2 min after tracheal intubation. Further measurements were taken before, and 30 s and 2 min after extubation. The increase in intra‐ocular pressure after intubation was greater in the glaucomatous group than in the normal group. The increase in intra‐ocular pressure was greater after extubation than intubation in both groups, but was similar in the two groups. However, because of the already increased intra‐ocular pressure in glaucomatous children, they may be at an increased risk of visual damage after intubation and extubation.
