Given the patient's body weight of 94.9 pounds, I would calculate the drug dosages using an ideal body weight rather than the actual body weight.
Gabapentin: 10 mg/kg PO
Cerenia 2 mg/kg PO
**Please give both drugs 2-3 hrs before the procedure if possible. This will help with sedation and it will be cheaper to give oral Cerenia then injectable Cerenia given the patient's size.
Hydromorphone: 0.05 mg/kg IV given slowly over 3 minutes
Propofol: 4-6 mg/kg IV
** If the patient is uncooperative for the catheter placement, dexmedetomidine can be administered at 3 mcg/kg IM with the hydromorphone at 0.05 mg/kg IM.
Induction: Propofol 4-6 mg/kg IV
**Provide 100% O2 via facemark during induction. I often give 1-2 mg/kg IV initially so the patient tolerates the face mask but continues to breathe spontaneously. Then titrate the remaining propofol to effect.
Maintenance: Isoflurane 1-2% or sevoflurane 2-3% with 100% O2
Fluid Therapy: 3mls/kg/hr with a balanced crystalloid
Dental Locoregional Techniques: Lidocaine or bupivicaine: 1 mg/kg. Allow >20 minutes for the blocks to take effect. I often perform them after the oral radiographs so they can take effect during the prophylactic cleaning.
If this patient is dysphoric in the post-operative period, you can give dexmedetomidine 0.5 mcg/kg IV or acepromazine 0.01 mg/kg IV. I typically have the doses pre-calculated and the drugs available with syringes just in case.
I recommend utilizing a portable pulse oximeter in the recovery period for monitoring, given the patient's age and weight. If the SpO2 drops below 95%, then flow-by O2 is recommended until the patient is able to maintain a SpO2 above 95%.
Pain Management: You can repeat the hydromorphone dose at 0.05 mg/kg IV or give buprenorphine 0.01 mg/kg IV if needed.
Ideally, we would not give a NSAID post-operatively because of the elevated liver enzymes.
