Abstract
Between February and September 2003, 136 (5.3%) of 2,558 patients undergoing cardiac surgery were supported with intra-aortic balloon counterpulsation. There were 71 infected (group 1) and 65 noninfected (group 2) patients. Risk factors for nosocomial infections were identified by univariate and multivariate analysis. On univariate analysis, significant risk factors were operation time, balloon pump duration, ventilation hours, duration of central venous catheter placement, amount of blood transfused, left ventricular ejection fraction < 30%, intra- and/or postoperative intra-aortic balloon counterpulsation, surgery under cardiopulmonary bypass, combined procedures, re-exploration, and Acute Physiology And Chronic Health Evaluation (APACHE) II score. On multivariate analysis, ventilation hours and amount of blood transfused were independently associated with group 1. Respiratory tract infections were common in the balloon counterpulsation population (41.1%). Mortality was significantly higher in patients needing balloon pump support (19.9%) compared to controls (1.1%), but it was similar in groups 1 and 2. Recognition of risk factors for postoperative infection in patients undergoing cardiovascular surgical procedures with intra-aortic balloon counterpulsation may help to improve their prognosis and allow more organized surveillance.

Abstract
The development of less invasive methods for myocardial revascularization such as "off-pump" cardiac surgery, and new methods of anesthesia and postoperative care protocols such as "fast-track recovery" (FTRC), have contributed to a significant reduction in postoperative intensive care unit (ICU) and hospital length of stay after cardiac surgical procedures. The objectives of this study were to identify perioperative risk factors of prolonged hospital stay, hospital mortality, and readmission rates in off-pump coronary artery bypass surgery (CABG) patients undergoing the FTRC protocol. Eighty consecutive patients undergoing off-pump coronary artery bypass surgery with FTRC protocol were included in the study. For the first purpose of this protocol, early extubation is defined as removal of the endotracheal tube within 6 h of arrival at the surgical ICU. The second purpose was to obtain a minimal length of stay in the ICU (<24 h) and hospital discharge within 5 days. We analyzed the influence of the preoperative, intraoperative, and postoperative variables on prolonged hospital stay, hospital mortality, and hospital readmission. Three patients died during hospitalization, giving a hospital mortality rate of 3.75%. The causes of hospital death were massive stroke and sepsis. Using multivariate logistic regression analysis, hypertension (P = 0.0185), postoperative stroke (P = 0.0001), and sternal infection (P = 0.0007) were identified as independent predictors of hospital mortality. Mean hospital length of stay was 4.23 +/- 0.75 days. Univariate and multivariate logistic regression analysis revealed that postoperative blood use (P = 0.0095) was the major independent predictor of prolonged hospital stay. During the 30-day observation period, seven patients were readmitted. One of these patients died on postoperative day 45 from mediastinitis and sepsis. Multivariate logistic regression analysis identified age (P = 0.0033) and hypertension (P = 0.045) as independent predictors of hospital readmission. FTRC protocols can be performed safely in patients with off-pump CABG, and the mortality and readmission rates following this protocol were found to be within acceptable ranges.

Abstract
OBJECTIVE To determine if the combined remifentanil and intrathecal morphine (RITM) anesthetic technique facilitates early extubation in patients undergoing coronary artery bypass graft (CABG) surgery. DESIGN Prospective, randomized, controlled clinical trial. SETTING Referral center for cardiothoracic surgery at a university hospital. PARTICIPANTS Patients (n = 24) undergoing first-time elective CABG surgery. INTERVENTIONS Two groups represented RITM (n = 12) and fentanyl-based (controls, n = 12) anesthesia. Premedication was standardized to temazepam, 0.4 mg/kg, and anesthesia was induced with etomidate, 0.3 mg/kg, in both groups. The RITM group received remifentanil, 1 microg/kg bolus followed by 0.25 to 1 microg/kg/min infusion, and intrathecal morphine, 2 mg. The control group received fentanyl, 12 microg/kg in 3 divided doses. Anesthesia was maintained with isoflurane and pancuronium in both groups. After completion of surgery, the remifentanil infusion was stopped. Complete reversal of muscle relaxation was ensured with a nerve stimulator, and a propofol infusion, 0.5 to 3 mg/kg/h, was started in both groups. All patients were transferred to the intensive care unit (ICU) to receive standardized postoperative care. Intensivists and ICU nurses were blinded to the group assignment. Propofol infusion was stopped, and the tracheal extubation was accomplished when extubation criteria were fulfilled. MEASUREMENTS AND MAIN RESULTS Both groups were similar with respect to demographic data and surgical characteristics. Extubation times were 156 +/- 82 minutes and 258 +/- 91 minutes in the RITM and control groups (p = 0.012). Patients in the RITM group exhibited lower visual analog scale pain scores during the first 2 hours after extubation (p < 0.04). Morphine requirements during the 24 hours after extubation were 2.5 +/- 3 mg in the RITM group and 16 +/- 11 mg in the control group (p = 0.0018). Sedation scores were lower in the RITM group during the first 3 hours after extubation (p < 0.03). Pulmonary function tests as assessed by spirometry were better in the RITM group at 6 and 12 hours after extubation (p < 0.04). There were no significant differences in PaO(2) and PaCO(2) after extubation between the 2 groups. None of the patients had episodes of apnea during the immediate 24-hour postextubation period. Two patients from the RITM group required reintubation on the second and sixth postoperative days. There were no differences in ICU and hospital length of stay between the 2 groups. CONCLUSION Implementation of the RITM technique provided earlier tracheal extubation, decreased level of sedation, excellent analgesia, and improved spirometry in the early postoperative period. The impact of RITM on ICU and hospital length of stay and potential cost benefits require further evaluation.

Abstract
The use of nonphysician-directed protocols and guidelines for the management of sedation and weaning has been shown to reduce the duration of mechanical ventilation for patients with acute respiratory failure when compared with conventional physician-directed practices. Practitioners in ICUs frequently are needed to perform multiple tasks and to evaluate numerous elements of clinical information in the care of the critically ill. In this complex environment, protocols and guidelines are one strategy for ensuring that specific tasks are carried out in a timely manner. Simple-to-employ methods for facilitating changes and improvements in the care of hospitalized patients recently have been proposed. These methods emphasize the importance of developing a culture of cooperation within the ICU so protocols and guidelines can be implemented successfully. Such a culture should embrace changes in medical practices in the ICU if they are associated with improved clinical outcomes. The results of studies evaluating the use of protocols and guidelines have important implications for general critical care practices, because many ICUs do not have physicians who are constantly at the patient's bedside. The need for effective communication from the bedside caregiver (e.g., nurse, respiratory therapist, pharmacist, technician) to the physician, so that treatment orders can be changed appropriately, usually results in some delay in the implementation of treatment changes. Protocols are one method for potentially reducing those delays and ensuring that medical care is administered in a more standardized and efficient manner.

Abstract
OBJECTIVE To compare the emotional state during the first 3 days after coronary artery surgery of patients who had undergone early versus conventional extubation. DESIGN A prospective, randomized, controlled trial. SETTING University hospital, single center. PARTICIPANTS Eligible patients (n = 100) presenting for elective coronary artery surgery, randomized to an early extubation group or a conventional extubation group. INTERVENTIONS Emotional status was measured by the Hospital Anxiety and Depression Scale (HAD), the Self Assessment Manikin (SAM), and the Multiple Affect Adjective Check List-Revised (MAACL-R). Tests were administered preoperatively and on the 1st and 3rd days postoperatively. MEASUREMENTS AND MAIN RESULTS Of patients in the conventional extubation group, 30% showed moderate-to-severe depressive symptoms (HAD score >10) on day 3 postoperatively compared with 8% of patients in the early extubation group (p = 0.02). There was a clinically insignificant increase in MAACL-R depression score on the 1st postoperative day within both groups but no other differences within or between groups in SAM or MAACL-R scores. CONCLUSION Early extubation results in fewer patients displaying depressive symptoms on the 3rd postoperative day but appears to have little effect on other measurements of emotional status. Anesthetic management during coronary artery bypass graft surgery may play an important role in the overall well-being of the patient by decreasing the incidence of postoperative depression.

Abstract
BACKGROUND Increasing hospital costs, restricted resources, and new surgical strategies have stimulated effectiveness of all routines in cardiac surgery. Over a 10-year period, 5,658 consecutive patients undergoing coronary artery bypass grafting followed a protocol aiming at short postoperative intubation times and rapid physical rehabilitation. METHODS The patients were prepared for rapid recovery, emphasizing (1) preoperative education and respiratory training, (2) low-dose fentanyl anesthesia, (3) limited ischemic times and pump times, (4) mild hypothermia and rewarming to a rectal temperature of 36 degrees C, (5) restricted use of extended monitoring, (6) autologous blood salvage to avoid allogeneic blood transfusions, and (7) active physical training from postoperative day 1. All in-hospital data relevant to these steps were prospectively stored in a database. RESULTS The median extubation time after arrival in the intensive care unit was 1.5 hours (0 to 320 hours). More than 99% of the patients were extubated within 5 hours. Sixty-two patients (1.1%) were reintubated and ventilated for a median of 24 hours (1 to 430 hours), mostly due to resternotomy for bleeding or cardiopulmonary decompensation. In total, 5,594 patients (98.9%) were able to sit in a chair the first postoperative day. Within the fourth postoperative day, 82.5% were able to move freely in the hospital area and were in fact physically fit for hospital discharge. Allogeneic blood products were given to 3.9% of the patients. Twenty-three patients (0.41%) died in-hospital. CONCLUSIONS With the application of a protocol for rapid physical recovery in patients undergoing "on-pump" coronary artery bypass grafting, extubation within 1 to 2 hours was safe and feasible in most patients. After 5 hours, 99.3% of the patients were extubated, with a reintubation rate of 1.1%. More than 80% of the patients were fully physically mobile within 4 days after the operation.

Abstract
OBJECTIVES Evaluation of the cost of propofol used for fast-track in cardiac surgery and its impact on global cost of management for anaesthesia and intensive care. STUDY DESIGN Case-control study, prospective (1998) and retrospective (1994). PATIENTS Twenty patients operated for cardiac surgery in 1998 and scheduled for fast-track anaesthesia. Twenty patients in 1994 matched for different criteria to the patient of 1998. METHODS In 1998, all drugs, materials used and X-rays, biochemical assays performed were prospectively collected and their cost calculated. In 1994, similar calculations were done retrospectively. Comparison of duration of mechanical ventilation, hospitalization in intensive care and in the hospital were performed. RESULTS Cost of anaesthesia was similar in 1994 and 1998 (2,646 FF versus 2,294 FF). Global cost of management was significantly lower in 1998 in comparison to 1994 (5,439 FF versus 8,558 FF). Duration of mechanical ventilation, hospitalization in intensive care and in the hospital were shorter in 1998 than in 1994. CONCLUSION Despite a higher cost of propofol for anaesthesia and postoperative sedation in comparison to midazolam, the global cost of management decreased significantly in relation to a one day decrease in hospitalization in the intensive care unit.

Abstract
OBJECTIVE To assess hemodynamic stability, postoperative pain management, and the control and timing of early extubation of a total intravenous anesthetic technique using propofol target-controlled infusion (TCI) and remifentanil in cardiac surgery. DESIGN Prospective study. SETTING University hospital. PARTICIPANTS Fifty patients scheduled for elective cardiac surgery. INTERVENTIONS Premedication consisted of oral midazolam, 0.1 mg/kg. Anesthesia was induced with propofol TCI at a target concentration of 1.5 to 2 microg/mL; remifentanil, 1 microg/kg; and rocuronium. Anesthesia was maintained with propofol at the same target concentration and remifentanil titrated between 0.25 and 1 microg/kg/min. Thirty minutes before the end of surgery, a 0.1-mg/kg bolus of morphine was administered intravenously. Postoperative sedation was achieved by maintaining the propofol infusion until the patient was deemed ready for extubation. Postoperative pain relief was evaluated using a visual analog scale. The intervals between arrival in the intensive care unit, spontaneous ventilation, and extubation were recorded. MEASUREMENTS AND MAIN RESULTS Included in this study were 36 men and 14 women (American Society of Anesthesiologist = III; New York Heart Association = II) scheduled for cardiac surgery. All patients remained hemodynamically stable throughout the perioperative period. Thirty-seven patients were successfully extubated during the first 4 postoperative hours. Spontaneous breathing was achieved at a mean interval of 15+/-5 minutes after propofol discontinuation. The mean interval to extubation was 163+/-45 minutes after arrival in the intensive care unit. Extubation was performed 48+/-12 minutes after patients were considered ready to awaken. During spontaneous ventilation, 36 patients received additional boluses of morphine (mean, 2.5+/-1 mg). Subsequently, all patients achieved a visual analog scale less than 40 mm. CONCLUSION The combination of remifentanil and propofol TCI resulted in hemodynamic stability and good postoperative analgesia. This technique allows physicians to schedule the time of extubation in patients undergoing cardiac anesthesia.

Abstract
STUDY OBJECTIVES To determine the safety of early extubation (EE) after coronary artery surgery. DESIGN Prospective randomized controlled trial. SETTING The cardiac surgery operating room and ICU of a university-affiliated teaching hospital. PATIENTS One hundred eligible patients presenting for elective coronary artery surgery. INTERVENTIONS Patients randomized to the EE group were administered a reduced dose of fentanyl (15 microg/kg) and an anesthetic compatible with EE, while patients randomized to the conventional extubation (CE) group were given fentanyl (50 microg/kg). MEASUREMENTS AND RESULTS The time to extubation in the EE group (median, 240 min; range, 30 to 930 min) was significantly less than the CE group (median, 420 min; range, 125 to 1,140 min) (p<0.01). Twenty patients were withdrawn from the study according to protocol guidelines. There were no cases of reintubation or complications attributable to EE. CONCLUSIONS By using an appropriate anesthetic technique and postoperative management, EE can be achieved following coronary artery bypass surgery without major complications.

Abstract
The anesthetic management of a patient with myasthenia gravis (MG) who underwent cardiac surgery with hypothermic cardiopulmonary bypass (CPB) is described. Using total intravenous anesthesia with propofol and a moderate dose fentanyl, the variations of neuromuscular function and serum anti-acetylcholine receptor antibody concentration were examined in relation to hypothermic CPB in the absence of muscle relaxants. The anesthetic technique used may have helped to avoid the risks incidental to muscle relaxants in this patient with MG undergoing hypothermic CPB.

Abstract
STUDY OBJECTIVE To evaluate the relationship between nosocomial infections and clinical outcomes following cardiac surgery, and to identify risk factors for the development of nosocomial infections in this patient population. DESIGN Prospective cohort study. SETTING Barnes-Jewish Hospital, St. Louis, a university-affiliated teaching hospital. PATIENTS Six hundred five consecutive patients undergoing cardiac surgery. INTERVENTIONS Prospective patient surveillance and data collection. MAIN OUTCOME MEASURES Occurrence of nosocomial infections, multiorgan dysfunction, hospital mortality, and risk factors for the acquisition of nosocomial infections. RESULTS One hundred thirty-one (21.7%) patients acquired at least one nosocomial infection following cardiac surgery. Four independent risk factors for the development of a nosocomial infection were identified: the duration of mechanical ventilation, postoperative empiric antibiotic administration, the duration of urinary tract catheterization, and female gender. Thirty (5.0%) patients died during their hospitalization. The mortality rate of patients acquiring a nosocomial infection (11.5%) was significantly greater than the mortality rate of patients without a nosocomial infection (3.2%) (odds ratio [OR]=4.0; 95% confidence interval [CI]=2.7 to 5.8; p<0.001). Multiorgan dysfunction was found to be the most important independent determinant of hospital mortality (adjusted OR=23.8; 95% CI=13.5 to 42.1; p<0.001) along with the aortic cross-clamp time (adjusted OR=2.3; 95% CI=1.7 to 3.0; p=0.002) and severity of illness as measured by APACHE II (acute physiology and chronic health evaluation) (adjusted OR=1.1; 95% CI=1.1 to 1.2; p=0.019). Ventilator-associated pneumonia, clinical sepsis, female gender, the cardiopulmonary bypass time, and severity of illness were identified as independent risk factors for the development of multiorgan dysfunction. Among hospital survivors, patients acquiring a nosocomial infection had longer hospital lengths of stay compared to patients without a nosocomial infection (20.1+/-13.0 days vs 9.7+/-4.5 days; p<0.001). CONCLUSIONS Nosocomial infections, which are common following cardiac surgery, are associated with prolonged lengths of hospitalization, the development of multiorgan dysfunction, and increased hospital mortality. These data suggest potential interventions for the prevention of nosocomial infections following cardiac surgery that could substantially improve patient outcomes and decrease medical care costs.

Abstract
OBJECTIVES Sedation and ventilation overnight after cardiac surgery is common practice. However, early extubation may be feasible with no increase in postoperative complications. This study examines (1) if early extubation is possible in a significant number of patients, (2) if it reduces ICU stay, and (3) if this practice increases postoperative complications. DESIGN Prospective, controlled, randomized clinical trial. PATIENTS AND METHODS We randomized 404 consecutive patients to early extubation (7 to 11 h postoperatively) (group A, 201 patients) or conventional extubation (between 8 and 12 AM the following day) (group B, 203 patients). Variables included type and severity of the disease, surgical risk, type of operation, operative incidences, postoperative complications, duration of mechanical ventilation, intubation and ICU stay, bleeding, reoperation, vasoactive drugs, and mortality. RESULTS Groups were comparable. Extubation within the preestablished time was successful in 60.2% of patients in group A and 74.4% in group B. Median ICU stay was 27 h in group A and 44 h in group B (p=0.008). Discharge from ICU within the first 24 h postoperatively was 44.3% in group A and 30.5% in group B (p=0.006). There was no significant difference in complications between groups. Successfully extubated patients in group A had more reintubation and prolonged ventilation than in group B. CONCLUSIONS (1) Sixty percent of our patients were extubated within 11 h of operation. (2) As a result, the length of stay in ICU was reduced and the percentage of patients discharged within 24 h was increased. (3) There was no increase in clinically important postoperative complications.

Abstract
BACKGROUND Poor pulmonary reserve is a risk factor that is used to exclude some patients from major operations. However, the value of routine spirometry in patients undergoing cardiac operations has not been widely evaluated. METHODS The outcomes of 586 consecutive adult patients undergoing cardiac operations were reviewed retrospectively to assess predictors of longer duration of endotracheal intubation. RESULTS By univariate analysis, congestive failure (p < 0.001), cardiomegaly (p = 0.002), recent myocardial infarction (p = 0.039), priority of operation (p = 0.005), previous cardiac operation (p < 0.001), and renal insufficiency (p = 0.002) increased the risk of longer endotracheal intubation. Spirometry (forced vital capacity, forced expiratory volume at 1 second, the ratio of forced expiratory volume at 1 second to forced vital capacity) did not correlate with longer endotracheal intubation. Perioperative complications, such as myocardial infarction (p < 0.001), coma, reexploration for bleeding, and reduced cardiac output (p < 0.001 each), correlated with longer duration of intubation. By multiple regression, priority of operation (p = 0.03), congestive failure (p = 0.02), and previous cardiac operation (p = 0.005) among preoperative risks and bleeding, reduced cardiac output, stroke, coma, and MB fraction of creatine kinase released postoperatively (p < 0.001 each) predicted longer duration of endotracheal intubation. CONCLUSIONS Postoperative cardiac function and the occurrence of complications are more significant than preoperative pulmonary function in determining the duration of endotracheal intubation after cardiac operation. Routine spirometry is probably unnecessary for most adult cardiac patients.
