【 摘 要 】

1. Patient Information Communication Form; Fill with the following details and send to CICU at least 45 minutes before patient shifting; patient’s demographics, diagnosis / procedure, ventilator settings (e.g. SIMV 12-14 cmH2O, TV 6-8 ml/kg, FiO25-0.6, PS 12-15 cmH2O, PEEP of 5 cmH2O, monitoring, inotropes, sedation, extubation plan 2. Handover of the patient from OR Anesthesia team to CICU team (Consultant, resident, attending nurse) a. Patient Handover details:   Demographics   Diagnosis/ Procedure.   Angiography findings (EF), Echo report (EF, valve functions, valve area, pulmonary hypertension)  Airway assessment  Comorbids b. Significant intraoperative events (e.g. hypotension, arrhythmias, blood transfusions etc.) c. I/V access d. Monitoring lines, If PA (indication) e. Last lab reports (Hb, ABGs, K) f. Ionotropic support, vasopressor use g. Pacing (indication, rate, mode) h.Temperature on shifting i. Extubation plan; fast track or conventional j. (Fast track: Extubation within 6 hours of arrival at CICU) 3. Warming measures (K+, normothermia, fluid warmer, room temp 22○C) activated. 4. Observation for two hours for chest tube output for weaning readiness. 5. Readiness testing: a. Stable hemodynamics SBP > 90 mm/Hg with minimal Ionotropic support (Epinephrine 200 on FiO2 of 0.5), pH > 7.30. c. Chest tube output 8 gm/dl. d. Peripheral Temp > 35.5 ºC 6. Weaning: a. Sedation off, after patient has some spontaneous breathing efforts b. Adequate analgesia supplementation (multi-modal approach) c. Reduce FiO2 to 0.4 if PO2 > 60 and oxygen saturation > 94%. d. Reduce SIMV slowly by 1-2 breaths every 10-15 min with close watch on patient’s hemodynamics, respiratory parameters (R/R, SpO2, TV). e. Put patient on spontaneous breathing with pressure support and monitor RSBI. f. Reduce PS to 8 slowly provided RSBI < 80.Do ABGs to see adequacy of oxygenation/ ventilation/metabolic status. 7. Extubation: if patient fully awake, cooperative, adequate cough and gag reflexes, adequate hand grip, minimal bronchial secretions. Caution: Extubation in the presence of anesthesia resident/consultant.
