* **회복기**: 회복하는 동안 반려동물을 조용하고 어두운 환경에 두십시오. 약효가 떨어질 때 놀람 반응, 불규칙한 움직임 또는 환각을 방지하기 위해 큰 소리, 갑작스러운 움직임 및 과도한 만짐을 최소화하십시오.

MLK (morphine/lidocaine/ketamine) mixture
투여 방법
IVIMSCPOIPSublingual (spray)
가능한 부작용
Hypertension
Hypersalivation
Respiratory depression (at high doses or rapid IV administration)
Hyperthermia (especially in cats)
Emesis
Vocalization
Erratic and prolonged recovery (emergence delirium)
Dyspnea
Spastic jerking movements and muscular tremors
Seizures (up to 20% of cats at therapeutic doses)
Hypertonicity and opisthotonos
Cardiac arrest
Pain after IM injection
Eyes remain open (risk of corneal drying/ulceration)
주의사항 및 금기
Prior hypersensitivity reactions to ketamine
Animals intended for human consumption
Use as a sole agent for major surgery (due to poor muscle relaxation and visceral analgesia)
Increased cerebrospinal fluid (CSF) pressure or head trauma
Significant hypertension, heart failure, or arterial aneurysms
Hypertrophic cardiomyopathy (HCM) in cats
Increased intra-ocular pressure or open globe injuries (relative)
Procedures involving the pharynx, larynx, or trachea (relative)
Preexisting seizure disorders (use with extreme caution)
Animals whose eyes are at risk of perforation
Raised intraocular pressure (IOP)
Raised intracranial pressure (ICP)
약물 상호작용
Chloramphenicol (parenteral): May prolong the anesthetic actions of ketamine
CNS Depressants (Narcotics, barbiturates, diazepam): May prolong the recovery time after ketamine anesthesia
Halothane: Recovery rates may be prolonged and the cardiac stimulatory effects of ketamine may be inhibited; close monitoring of cardiac status is recommended
Ivermectin: Recommended not to use ivermectin in reptiles within 10 days of ketamine
Neuromuscular blockers (e.g., succinylcholine, tubocurarine): May cause enhanced or prolonged respiratory depression
Thyroid hormones: May induce severe hypertension and tachycardia; beta-blockers may be of benefit in treating these effects
Alpha-2 adrenergic agonists (e.g., medetomidine, dexmedetomidine): Synergistic anaesthesia and prevention of muscle hypertonicity. Reversal of the alpha-2 agonist must be delayed until 45 minutes after ketamine administration to prevent unopposed ketamine excitation.
Benzodiazepines: Synergistic anaesthesia and prevention of ketamine-induced skeletal muscle hypertonicity.

> **Cardiovascular Caution**: Ketamine increases heart rate, blood pressure, and myocardial oxygen consumption. Avoid in patients where this is detrimental (e.g., unstable shock, congestive heart failure, hypertrophic cardiomyopathy).
> **Ocular Care**: Cats' eyes remain open after receiving ketamine. Protect from injury and apply an ophthalmic lubricant (e.g., Lacri-Lube) to prevent excessive corneal drying.
* **Hepatic/Renal Insufficiency**: Use with caution. In cats, ketamine is excreted almost exclusively via the kidneys; reduce doses or use cautiously in feline renal disease.
* **Sympathetic Tone**: Use with caution in animals with preexisting increased sympathetic tone (e.g., pheochromocytoma, hyperthyroidism).
* **Recovery**: Minimize exposure to handling or loud noises during the recovery period to reduce the incidence of emergence reactions (delirium, thrashing), but continue to monitor vital signs closely.
* **Hemorrhage**: Because ketamine can increase blood pressure, careful control of post-surgical hemorrhage (e.g., declawing) is required.
