Background: Fast-track cardiac anesthesia refers to extubation within 6 h of the end of surgery, whereas ultra-fast-track anesthesia (UFTA) refers to extubation within 2 h of the end of surgery. Objectives: We have tested a protocol for early extubation to see safety, efficacy of ultra-fast tracking, and its cost containment in the present study of forty patients in cardiac surgery department in a tertiary care rural center. Materials and Methods: We have observed in our study the outcome of UFTA on a set of forty patients posted for cardiac surgery, using a protocolized approach and have prospectively noted the duration of mechanical ventilation, extubation time, length of Intensive Care Unit (ICU) stay, rate of re intubation, and other complication. Results: Extubation could be achieved within 30 min in 29 patients (72.5%). Mean length of ICU stay could be cut to 1.6 days (39 h). 55% patients could be mobilized on postoperative day 1, With approximate cost savings of 5000 rupees/patient/day. No cases of reintubation or serious complications noted. Conclusion: Ultra-fast-tracking is found to be feasible in our cardiac surgical setup. It is safe in all age groups, with proper selection of cases and rational utilization of available resources, besides it is found to be cost-effective.

| Introduction|| |
Fast tracking implies implementation of perioperative patient care programs that ultimately reduce the time of hospital discharge and early resumption of activities after any major or a minor surgical procedure. It is gaining importance because of rapid mobilization, less morbidity, early discharge, better patient comfort, and economic concerns. Fast-track cardiac anesthesia (FTCA) refers to extubation within 6 h of the end of surgery, whereas ultra-fast-track anesthesia (UFTA) refers to extubation within 2 h of the end of surgery.
We have prepared a protocol of perioperative management in cardiac anesthesia for ultra-fast-tracking. Our aim was to test the feasibility of this protocol for UFTA in our cardiac center.
Following parameters were applied for testing the protocol.
(1) Time to extubation, (2) Length of Intensive Care Unit (ICU) stay, (3) Incidence of complications, (4) Cost-effectiveness of this technique.
| Materials and Methods|| |
It is a prospective observational (case series) done in the period of April 2013–October 2013 on a set of forty patients posted for cardiac surgery.
- Age 1–70 years
- Cross-clamp time <120 min
- Ejection fraction (EF) >30%
- Open heart surgical cases, off pump coronary artery bypass graft (CABG).
- Poor left ventricular function with intraaortic balloon pump support
- Comorbidities + (hepatic or renal failure, creatinine >1.5, h/o convulsions, tuberculosis, or asthma)
- Emergency surgery
- Combined procedure (i.e., CABG + other heart/vascular procedure)
- Redo surgery.
On-table extubation criteria
- Patient awake, responsive, and cooperative
- Vital capacity >6 ml/kg
- Transesophageal echocardiography (TEE) findings are normal.
- PaO2>80 mmHg on FiO2≤0.5, pH 7.35–7.45
- Temperature >36.5°C
- Absence of uncontrolled dysrhythmia
- Minimal chest tube drainage.
Note: If on-table extubation is not achieved à patient was extubated within 2 h, postoperatively if fulfilling the above criteria.
We have implemented a multidisciplinary approach wherein the surgeons' cooperation in view of fast and precise surgery, anesthetist for their selected anesthetic technique, and perfusionist for some favorable modifications in cardiopulmonary bypass (CPB).
| Results|| |
Extubation could be achieved within 30 min in 29 patients (72.5%), 19 out of 22 congenital heart disease could be extubated on table (86%). Two cases could not be extubated early within 2 h. Reasons for late extubation were high-surgical drains, which was not related to our anesthetic technique. Mean length of ICU stay could be cut down to 1.8 days. 40% patients mobilized on the day of surgery. 55% patients could be mobilized on postoperative day 1and remaining 5% on day 2. No cases of reintubation or serious complications except two cases which had ICU psychosis and one case having atrial fibrillation which was manageable, with approximate cost savings of 5000 rupees/patient/day.
The results of the study are depicted in figure formats [Figure 1], [Figure 2], [Figure 3] and tabular formats [Table 1], [Table 2], [Table 3], [Table 4], [Table 5], [Table 6], [Table 7], [Table 8], [Table 9], [Table 10], [Table 11], [Table 12]
| Discussion|| |
Cardiac anesthesia like most other medical disciplines has undergone many transformation over the years. High-dose opioids have been traditionally used in cardiac anesthesia mainly because of the cardio stability that they provide. It requires postoperative mechanical ventilation until the patient's blood gas status, temperature, and hemodynamics were stabilized. In the 1990s, due to financial constraints on medical services, the focus of cardiac anesthesia has shifted to low-opioid techniques, wide use of short-acting anesthetic drugs, and multimodal analgesic techniques. This facilitated faster recovery, early extubation, and shorter ICU stay and reduction in cost. Fast tracking has become a relatively accepted method now in cardiac anesthesia.
As quoted by Barash et al., “in this era of cost containment any technique that allows maximal use of resources without jeopardizing patients safety is welcome.” This statement is even more true today when hospitals are struggling with increasing medical expenses. Although fast-track anesthesia was introduced in 1990s, still large multicentre trials confirming its potential benefits have not being developed. Thus, concerns about the safety of these technique still remain [Figure 1], [Figure 2], [Figure 3].
This study was carried out in the operating rooms (OR) and ICU of our center, belonging to a rural hospital, which has a high-cardiac patients flow particularly from a low-socioeconomic status; Hence, we needed ICU beds, reduction in cost of surgery, and reduction in hospital stay. Such a protocol was the need of the hour. Our approach was goal directed with favorable cooperation from the surgeon (speed and precision, use of standardized surgical technique, minimizing cross clamp time, adequate hemostasis, and less surgical errors) and that of perfusionist team also.
The role of cardiac anesthetist is the key to successful outcome that includes from patient selection, avoiding unnecessary us age of inotropes and blood products, efficient pain relief, and availability round the clock.
Our anesthetic strategies included the following:
We have followed safe CPB techniques, particularly the use of blood cardioplegia and maintenance of normothermia. Such modifications have been shown to reduce extubation time and lower hospital and ICU stay. We have included only cases which do not have prolonged cross-clamp time, <120 min as shown in our CPB data.
Use of nonopioid analgesia (dexmedetomidine, paracetamol) in postoperative period is always beneficial for early mobilization and patient comfort. We have found that faster mobilization is possible with use of less sedation in postoperative period which is a psychological boost the patient and their relatives. We have avoided thoracic epidural techniques which has reduced cost. Use of caudal blocks in pediatric patients has resulted in adequate analgesia in perioperative period reducing opioid dose.
Pediatric patients have been shown to benefit from early extubation. Extubation by UFTA mode in children has been known to reduce ICU stay and lesser use of hospital resources. Most children undergoing congenital heart surgery can be extubated in OR. Early extubation is associated with low-morbidity rates and shorter length of ICU stay. A study on intraoperative anesthetic management directed to early extubation in pediatric cardiac surgery has been shown to decrease pediatric ICU stay.
Although fast tracking in pediatric congenital heart disease cases has been practiced safely significant individual and institutional concerns about the safety still exists. In this study, we have successfully fast-tracked pediatric surgery cases (86% on table extubation).
Whereas adult cardiac cases are being done without adverse outcome by fast-track anesthesia technique. In the elderly patients, UFTA is been found to be safe with careful selection of cases. In our study, we have included patients of different age group. Elderly patients included in our study are the one having EF >30% and no comorbidities.
In an earlier study, immediate extubation has not been shown to cause any complications when compared to use of conventional strategies in other patients. Reintubation was not done in any of our UFTA patient. Studies have shown no difference in reintubation rates in fast-tracked patients compared to conventional management., Reported rate of reintubation following early extubation in patients with congenital heart disease is typically very low, 2%–3%. There is no evidence of increased morbidity or mortality with FTCA technique as compared to traditional high-dose opioid technique. Studies have proven that extubation in the OR can be safely performed in cardiac surgery cases without any increase in morbidity and mortality [Table 1], [Table 2], [Table 3], [Table 4], [Table 5], [Table 6].
Benefits of early extubation, particularly in CABG patients, include improved cardiac function and reduction in ICU stay, thus saving patient cost, shorter length of hospital stay, and cost savings compared with national data were observed after implementation of fast tracking in cardiac anesthesia. Cheng et al. designed a prospective randomized trial to evaluate the total cost savings of early extubation which was about 9% per CABG case in uncomplicated surgeries. As observed in the study, it is definitely a cost-effective technique [Table 7]. A total of forty patients were observed in our study, of which 38 patients were successfully extubated within 2 h of the surgery [Table 8], [Table 9], [Table 10], [Table 11], [Table 12].
Limitations of this case series
- Number of cases were limited
- Long-term risk not observed.
| Conclusion|| |
Ultra-fast-tracking was found feasible in our rural center which is still developing. With proper selection of cases, rational utilization of available resources (drugs, TEE, trained theater, and nursing staff) and management as a teamwork resulted in successful outcome. We found it applicable in a wide range of age group, pediatric as well elderly. Excellent outcome i/v/o faster patient mobilization, improved patient comfort and cooperation, and reduced postoperative morbidity. Cost containment of this technique deserves particular mention as our medical services are increasingly struggling with limited resources as opposed to ever increasing patient load.
