Emergence agitation is the most common reason for post-anesthesia care unit delay. Sevoflurane is used frequently inhalational anaesthetic agent to provide pediatric anaesthesia because of the nonirritant nature. It has been successfully used for keeping spontaneous breathing without tracheal intubation. However, sevoflurane may cause emergence agitation as the incidence varied from 10%-80%. Although there are many sedative agents to reduce its incidence, such as propofol, midazolam, a2 adrenergic receptor agonists and ketamine, the efficacy remains limited.
Ketamine, a neuroleptic anesthetic agent, contains two optical isomers, s(+)-ketamine (esketamine) and R(-)-ketamine. Esketamine is a right-handed split of ketamine, which has enhanced analgesic potency and lower incidence of psychotropic side effects compared to ketamine. It stimulate breathing due to N-Methyl-D-Aspartate receptor blockade, and could even effectively countered remifentanil-induced respiratory depression. The investigators compared the effectiveness of esketamine and sevoflurane in reducing the incidence of emergence agitation after painless ophthalmological procedure in pediatric patients.
Ophthalmological procedure such as suture remove, intraocular pressure (IOP) measurement, slit-lamp and fundoscopy are most frequently performed in operation with minor surgical stimulus, and the the duration of surgery is very short. Several anesthestic agents are available,but it is hard to balance short effect and fast rotation in post-anesthesia care unit.

Additionally, several studies have reported ketamine could reduced agitation, but there is no study about esketamine on emergence agitation.

|---|---|---|---|
| Group E | Experimental | 1ug· kg-1 dexmedetomidine and 0.01mg·kg-1 atropine was administered intravenously. 0.25mg·kg-1 esketamine was administered by vein in one minute, and 0.25mg·kg-1 esketamine was given at the beginning of the surgery. |
|
| Group S | Active Comparator | 1ug· kg-1 dexmedetomidine and 0.01mg·kg-1 atropine was administered intravenously. 4% sevoflurane(FIO2=100%, 3L·min-1) was used to induce anesthesia by mask inhalation and 2-4 % sevoflurane (adjusted according to the depth of the anaesthesia,FIO2=100%, 2L·min-1) was maintained. |
