Can Cardiac Surgery Lead to ICD-11 PTSD and Complex PTSD? Findings of a 5-year Follow-up Study.

Cardiac surgery may lead to various neuropsychiatric conditions, including posttraumatic stress disorder (PTSD). The 11th revision of the International Classification of Diseases (ICD-11) included a new complex posttraumatic stress disorder (CPTSD) disorder in addition to PTSD. This study aimed to explore whether cardiac surgery could be associated with PTSD and CPTSD at a five-year follow-up after cardiac surgery. The study sample comprised 210 patients (mean age 67, 69.5% male) who had undergone cardiac surgery. The self-report International Trauma Questionnaire (ITQ) was used to assess ICD-11 PTSD and CPTSD. The Medical Outcomes Study 36 Item Short Form Health Survey (SF-36) questionnaire was used to measure health-related quality of life (HRQOL). We found 5.2% of cardiac surgery-related probable PTSD and CPTSD at a 5-year follow-up, 1.9% PTSD, and 3.3% CPTSD. Low HRQOL was associated with a high risk for PTSD/CPTSD at follow-up. The results showed that cardiac surgery might have a long-term effect on PTSD and CPTSD symptoms. Patients with low HRQOL are at higher risk of having PTSD/CPTSD risk. The study informs about the need for psychosocial interventions to reduce the impact of cardiac surgery on neuropsychiatric conditions and the improvement of HRQOL.

Outcomes and Risk Factors of Critically Ill Patients with Hematological Malignancy. Prospective Single-Centre Observational Study.

Background and Objectives: Oncohematological patients have a high risk of mortality when they need treatment in an intensive care unit (ICU). The aim of our study is to analyze the outcomes of oncohemathological patients admitted to the ICU and their risk factors. Materials and Methods: A prospective single-center observational study was performed with 114 patients from July 2017 to December 2019. Inclusion criteria were transfer to an ICU, hematological malignancy, age >18 years, a central line or arterial line inserted or planned to be inserted, and a signed informed consent form. Univariate and multivariable logistic regression models were used to evaluate the potential risk factors for ICU mortality. Results: ICU mortality was 44.74%. Invasive mechanical ventilation in ICU was used for 55.26% of the patients, and vasoactive drugs were used for 77.19% of patients. Factors independently associated with it were qSOFA score ≥2, increase of SOFA score over the first 48 h, mechanical ventilation on the first day in ICU, need for colistin therapy, lower arterial pH on arrival to ICU. Cut-off value of the noradrenaline dose associated with ICU mortality was 0.21 µg/kg/min with a ROC of 0.9686 (95% CI 0.93-1.00, p < 0.0001). Conclusions: Mortality of oncohematological patients in the ICU is high and it is associated with progression of organ dysfunction over the first 48 h in ICU, invasive mechanical ventilation and need for relatively low dose of noradrenaline. Despite our findings, we do not recommend making decisions regarding treatment limitations for patients who have reached cut-off dose of noradrenaline.

Predictors of long-term HRQOL following cardiac surgery: a 5-year follow-up study.

BACKGROUND: The study aimed to evaluate the long-term change of health-related quality of life (HRQOL) and to identify predictors of HRQOL 5 years after cardiac surgery. METHODS: Consecutive adult patients, undergoing elective cardiac surgery were enrolled in the study. HRQOL was measured using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) questionnaire before and 5-years after cardiac surgery. A multivariate latent change modeling approach was used for data analysis. RESULTS: 210 participants (30.5% female) were reached at 5-year follow-up and included in final data analysis. The study revealed, after controlling for gender effects, a significant long-term positive change, in physical functioning (PF, Mslope = 19.79, p < 0.001), social functioning (SF, Mslope = 17.27, p < 0.001), vitality (VT, Mslope = 6.309, p < 0.001) and mental health (MH, Mslope = 8.40, p < .001) in the total sample. Lower education was associated with an increase in PF (Mslope = 24.09, p < 0.001) and VT (Mslope = 8.39, p < 0.001), more complicated surgery (other than the coronary artery bypass graft (CABG) predicted increase in general health (GH, Mslope = 6.76, p = 0.005). Arrhythmia was a significant predictor for lower pre- and post-operative VT and SF. CONCLUSIONS: Overall HRQOL in our sample improved from baseline to five years postoperatively. Further studies including larger patient groups are needed to confirm these findings.

Acute Kidney Injury in Cardiac Surgery Patients: Role of Glomerular Filtration Rate and Fat-Free Mass.

SUMMARY BACKGROUND: eGFR (estimated glomerular filtration rate) formulas may be inaccurate in overweight cardiac surgery patients, overestimating the kidney reserve. The aim of this study was to modify the eGFR formulas and to determine whether the modified eGFR is a more accurate predictor of acute kidney injury (AKI). MATERIALS AND METHODS: The patients were assigned into 4 BMI groups as follows: normal weight (18.5- 25 kg/m2), pre-obesity (25-30 kg/m2), class I obese (30-35 kg/m2), class II and III obese (≥35 kg/m2). Cockcroft- Gault (CG) eGFR formula was modified by using the fat-free mass (FFM) derived from bioelectrical impedance. ROC-AUC curves were analyzed to identify the accuracy of the eGFR formulas (CG, CG modified with FFM, Mayo Clinic Quadratic equation, CKD-EPI, MDRD) to predict the AKI in each group. RESULTS: Although all of the used equations showed similar predictive power in the normal weight and overweight category, Mayo formula had the highest AUC in predicting the occurrence of AKI (ROC-AUC 0.717 and 0.624, p<0.05). However, in the group of patients with class I obesity, only the CG formula modified with a fat-free mass appeared to be predictive of postoperative AKI (ROC-AUC 0.631 p<0.05). None of the equations were accurate in the group of BMI (>35 kg/m2). CONCLUSIONS: eGFR is a poor predictor of AKI, especially in the obese patients undergoing cardiac surgery. The only equation with a moderate predictive power for the class I obese patients was the CG formula modified with the fat-free mass.

Impact of Immunonutrition on T Cell Activation: A Randomized Control Study in Cardiac Surgery Patients.

Background: Cardiac surgery provokes an intense inflammatory response that can cause an immunosuppressive state and adverse postoperative outcomes. We recently showed that postoperative immunonutrition with glutamine in "fragile" low-risk cardiac surgery patients was associated with a significantly increased level of CD3+ and CD4+ T cells. In order to clarify the biological relevance and clinical importance of these findings, we investigated whether an increase in the CD4+ T cell level was caused by changes in the systemic inflammatory response (caused by surgery or infection) and if it was associated with their activation status. Methods: A randomized control study of low operative risk but "fragile" cardiac surgery patients was performed. Patients were randomized into immunonutrition (IN) and control groups (C). The IN group received normal daily meals plus special immune nutrients for 5 days postoperatively, while the C group received only normal daily meals. Laboratory parameters were investigated before surgery and on the sixth postoperative day and the groups were compared accordingly. The expression of the CD69+ marker was investigated to determine T cell activation status. Serum concentrations of cytokines (interleukin-10 (IL-10), tumor necrosis factor α (TNF-α) and interleukin-6 (IL-6)) and C-reactive protein (CRP) were determined to assess the systemic inflammatory response, while procalcitonin (PCT) levels were evaluated to confirm or deny possible bacterial infection. Results: Fifty-five patients were enrolled in the study. Twenty-seven (49.1%) were randomized in the IN group. Results show that on the sixth postoperative day, the CD4+CD69+ and CD8+CD69+ counts did not differ between the IN and C groups, accordingly 0.25 [0.16-0.50] vs 0.22 [0.13-0.41], p=0.578 and 0.13 [0.06-0.3] vs 0.09 [0.05-0.14], p=0.178. Also, statistically significant differences were not observed in the cytokine levels (IN and C groups: TNF-α 8.13 [7.32-10.31] vs 8.78 [7.65-11.2], p=0.300; IL-6 14.65 [9.28-18.95] vs 12.25 [8.55-22.50], p=0.786; IL-10 5.0 [5.0-5.0] vs 5.0 [5.0-5.0], p=0.343 respectively), which imply that an elevated T cell count is not associated with the systemic inflammatory response. Also, PCT (IN and C groups: 0.03 [0.01-0.09] vs 0.05 [0.03-0.08], p=0.352) and CRP (IN and C groups 62.7 [34.2-106.0] vs 63.7 [32.9-91.0], p=0.840) levels did not differ between the two groups. Moreover, low levels of PCT indicated that the increase in T cell count was not determined by bacterial infection. Conclusions: Our findings showed that CD4+ T cell levels were associated with neither the systemic inflammatory response nor bacterial infection. Secondly, increases in T cells are not accompanied by their activation status. These results suggest a hypothesis that a higher postoperative T cell concentration may be associated with postoperative immunonutrition in low-risk cardiac surgery patients with intact cellular vitality, i.e. "fragile". However, immunonutrition alone did not affect T cell activation status.

The efficacy of early postoperative enteral immunonutrition on T-lymphocyte count: A randomised control study in low-risk cardiac surgery patients.

BACKGROUND: Patients undergoing cardiac surgery have a pronounced immune response that leads to a reduction in cellular immunity. Immune-modulating nutritional supplements are considered to be beneficial for patients undergoing major surgery. However, due to the lack of studies in the cardiac surgery population, the effect of immunonutrition remains unclear in this patient group. OBJECTIVE: Our purpose was to research the efficacy of early postoperative enteral immunonutrition on T-lymphocyte count in the cardiac surgery population. METHODS: This was a randomised control study of low operative risk adult patients, who underwent elective cardiac surgery. These patients were randomised into immunonutrition and control groups. The immunonutrition group was supplemented with immune nutrients for five postoperative days. The counts of T-lymphocytes, as well as the counts for the CD4+ and CD8+ cell subpopulations were determined on the day of surgery and on the sixth postoperative day. RESULTS: Fifty-five patients were enrolled in the study, the mean age was 69.7 ± 6.3 years, 28 (50.9%) of them were males, the median operative risk was 1.75%. Twenty-seven (49.1%) were randomised into the immunonutrition group. The control and the immunonutrition groups were similar before the intervention. The counts of the CD3+ T cells and CD4+ T cells on the sixth postoperative day were significantly higher in the immunonutrition group compared to the control group with 1.42 ± 0.49 vs. 1.12 ± 0.56 (∗109/l), p = 0.035 and 1.02 ± 0.36 vs. 0.80 ± 0.43 (∗109/l), p = 0.048, respectively. Regression analysis was performed to determine the efficacy of the immunonutrition on the counts of the CD3+ and CD4+ T cells; CD3+ T and CD4+ T cell counts were increased to 0.264 (∗109/l), p = 0.039 and 0.232 (∗109/l), p = 0.021, respectively. CONCLUSIONS: Early postoperative immunonutrition increases the count of the CD3+ and CD4+ T cells in cardiac surgical patients. Clinical trials identifier number: NCT04047095.

Long-term quality of life and posttraumatic stress following elective cardiac surgery: preliminary findings of a 5-year follow-up study.

BACKGROUND: Heart surgery is a major stressful event that can have a significant negative effect on patients' quality of life (QoL) and may cause long-term posttraumatic stress reactions. The aim of this pilot study was to estimate the longitudinal change and predictors of health-related quality of life (HRQOL) dynamics and identify factors associated with PTS at 5-year follow-up (T2) after elective cardiac surgery and associations with pre-surgery (T1) QoL. MATERIALS AND METHODS: Single-centre prospective study was conducted after Regional Bioethics Committee approval. Adult consecutive patients undergoing elective cardiac surgery were included. HRQOL was measured using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) questionnaire before (T1) and 5-years after (T2) cardiac surgery. Posttraumatic stress was assessed using the International Trauma Questionnaire. RESULTS: The pilot study revealed a significant positive change at 5-year follow-up in several domains of SF-36: physical functioning (PF), energy/fatigue (E/F), and social functioning (SF). Prolonged postoperative hospital stay was associated with change in SF (p < 0.01), E/F (p < 0.05) and emotional well-being (p < 0.05). The percentage of patients that had the posttraumatic stress disorder (PTSD) at T2 was 12.2%. Posttraumatic stress symptoms were associated with longer hospitalization after surgery (p < 0.01). CONCLUSIONS: HRQOL improved from baseline to five years postoperatively. Patients with lower preoperative HRQOL scores tended to have a more significant improvement of HRQOL five years after surgery. A prolonged postoperative hospital stay had a negative impact on postoperative social functioning, energy/fatigue, and emotional well-being. Increased levels of PTSD were found in cardiac surgery patients following five years after the surgery.

Bioelectrical Impedance Phase Angle-Predictor of Blood Transfusion in Cardiac Surgery.

OBJECTIVE: To determine whether bioelectrical impedance-derived phase angle (PA) can be a predictor of red blood cell (RBC) transfusion in patients undergoing cardiac surgery. DESIGN: An observational retrospective study of prospectively collected data. SETTING: Single center, tertiary referral university hospital. PARTICIPANTS: The study sample comprised 642 adult patients undergoing elective cardiac surgery. INTERVENTIONS: Patient demographic and clinical variables were collected. The body composition of the patients was evaluated by bioelectrical impedance analysis (BIA) the day prior to surgery. The rates of postoperative RBC transfusion were recorded. MEASUREMENTS AND MAIN RESULTS: Among the 642 patients (67.8% men, median age of 66 [range 59-73]) included in the present study, 210 (32.7%) received at least 1 RBC unit postoperatively. Hypertension, preoperative stroke, renal failure, preoperative hemoglobin and hematocrit values, BIA-derived PA, aortic crossclamp time, and cardiopulmonary bypass (CPB) time were associated with the risk of RBC transfusion in the univariate analysis, and were included in the final multivariate regression model. Preoperative stroke (odds ratio [OR] 0.394; 95% confidence interval [CI]: 0.183-0.848; p = 0.017), preoperative hemoglobin values (OR 0.943; 95% CI: 0.928-0.960; p < 0.001), PA <15th percentile (OR 2.326; 95% CI: 1.351-4.000; p = 0.002), and CPB time (OR 1.013; 95% CI: 1.008-1.018; p < 0.001) were identified as independent predictors of RBC transfusion. CONCLUSION: Several factors were identified to be associated significantly with postoperative RBC transfusion in patients undergoing cardiac surgery. Among the conventional predictors, the value of the BIA-derived PA was indicated as a potent prognostic tool.

Concordance of the new ESPEN criteria with low phase angle in defining early stages of malnutrition in cardiac surgery.

BACKGROUND & AIMS: The aim of this study was to evaluate the incidence of malnutrition (MN) in cardiac surgery patients by implementing the new ESPEN diagnostic criteria and to determine whether these criteria are concordant with the bioelectrical impedance analysis (BIA) provided phase angle (PA) in predicting early stages of malnutrition. METHODS: A prospective study was conducted in a tertiary hospital. The nutritional state of the cardiac surgery patients was evaluated one day prior to cardiac surgery using the malnutrition screening tools NRS-2002, MUST and SF-MNA, and bioelectrical impedance analysis. Patients at risk of malnutrition were further studied in accordance with the ESPEN malnutrition diagnostic criteria. A BIA provided PA value of less than the 15th percentile of the age and gender group was set as a theoretical marker of early malnutrition. ROC AUC (receiver operating characteristic area under curve) analysis and other parameters were calculated to determine the concordance between the new ESPEN malnutrition diagnostic criteria and a low PA. RESULTS: The study comprised 549 enrolled cardiac surgery patients. MN or risk of MN in accordance with at least one nutritional status assessment tool was diagnosed in 372 (67.75%) patients. MN, according to the new ESPEN malnutrition diagnostic criteria, was only diagnosed in 31 (5.6%) patients. Low PA was detected in 124 patients (22.6%), providing a higher MN rate. The ROC analysis and other concordance parameters showed that the new ESPEN diagnostic criteria (AUC 0.560, p = 0.042) were not concordant with a low PA. CONCLUSION: Fewer patients are classified as malnourished by the new ESPEN definition as those identified by the BIA provided PA. Incorporation of the BIA provided PA into the new ESPEN definition may aid to diagnose the early stages of MN in the field of cardiac surgery.

Intrathecal Baclofen Therapy for the Treatment of Spasticity in Lithuania.

Spasticity of cerebral or spinal origin severely impairs an individual's functional ability and quality of life. Intrathecal baclofen (ITB) therapy via an implantable pump is indicated for use in patients unresponsive to oral antispasmodics. ITB therapy improves the daily caring for and relief of painful spasms. In Lithuania, ITB therapy was introduced in clinical practice just recently. We share our experience of spasticity management with the ITB pump system in five patients at Vilnius University Hospital Santariskiu Klinikos. Four patients had spastic tetraplegia associated with cerebral palsy, and one patient developed spastic paraplegia after a spinal epidural abscess.

Malnutrition assessed by phase angle determines outcomes in low-risk cardiac surgery patients.

BACKGROUND & AIMS: Phase angle (PA), which is obtained from bioelectrical impedance analysis (BIA), is a non-invasive method for measuring altered electrical properties of biological tissues. It has been recognised as an objective prognostic marker of disease severity and frailty. The aim of this study is to determine whether PA is a marker of malnutrition and postoperative morbidity in low operative risk patients undergoing cardiac surgery. METHODS: A prospective study was conducted in a tertiary hospital. The nutritional state of the cardiac surgery patients was evaluated using BIA the day before the scheduled surgery. After applying selection criteria, 342 low operative risk patients were selected and classified into two groups in accordance with the PA value: a low PA group and a normal PA group. The correlation between low PA and low fat-free mass index (FFMI), a marker of malnutrition, was assessed. Associations between low PA and adverse postoperative outcomes, defined by the Society of Thoracic Surgeons postoperative risk evaluation model, were analysed. The impact of low PA on length of stay in an ICU and hospital was evaluated. RESULTS: Low PA was detected in 61 (17.8%) patients in the selected group, which consisted of low operative risk patients with a median Euroscore II value of 1.46 (IQR: 0.97-2.03) and was associated with FFMI with Pearson's R of 0.515 (p < 0.001). Low PA was associated with higher rates (13 [21.3%] vs. 30 [10.7%] p = 0.023) and risk of postoperative morbidity in univariate regression analysis (OR = 2.27, Cl 95% = 1.10-4.66, p = 0.026). Furthermore, low PA persisted as an independent factor in multivariate regression analysis (OR = 2.50, CI 95% 1.18-5.29, p = 0.016) adjusted for preoperative risk factors of postoperative morbidity. Evaluation of hospitalisation length revealed a tendency of a prolonged hospitalisation (>14 days) rate (31 [50.8%] vs. 105 [37.8%], p = 0.063) in the group with low PA. CONCLUSION: A low preoperative PA is an indicator of malnutrition and determines adverse outcomes after cardiac surgery. Further research is needed to evaluate clinical applications of the PA, such as a more accurate identification of malnourished cardiac surgery patients.

Preoperative risk factors of malnutrition for cardiac surgery patients.

BACKGROUND: Malnutrition (MN) is prevalent in cardiac surgery, but there are no specific preoperative risk factors of MN. The aim of this study is to assess the clinically relevant risk factors of MN for cardiac surgery patients. MATERIALS AND METHODS: The nutritional state of the patients was evaluated one day prior to surgery using a bioelectrical impedance analysis phase angle (PA). Two groups of patients were generated according to low PA: malnourished and well nourished. Risk factors of MN were divided into three clinically relevant groups: psychosocial and lifestyle factors, laboratory findings and disease-associated factors. Variables in each different group were entered into separate multivariate logistic regression models. RESULTS: A total of 712 patients were included in the study. The majority of them were 65-year old men after a CABG procedure. Low PA was present in 22.9% (163) of patients. The analysis of disease-related factors of MN revealed the importance of heart functions (NYHA IV class OR: 3.073, CI95%: 1.416-6.668, p = 0.007), valve pathology (OR: 1.825, CI95%: 1.182-2.819, p = 0.007), renal insufficiency (OR: 4.091, CI95%: 1.995-8.389, p < 0.001) and body mass index (OR: 0.928, CI95%: 0.890-0.968, p < 0.001). Laboratory values related to MN were levels of haemoglobin (OR: 0.967, CI95%: 0.951-0.983, p < 0.001) and C-reactive protein (OR: 1.015, CI95%: 1.002-1.028, p = 0.0279). The lifestyle variables that qualified as risk factors concerned the intake of food (OR: 3.030, CI95%: 1.353-6.757, p = 0.007) and mobility (OR: 2.770, CI95%: 1.067-7.194, p = 0.036). CONCLUSIONS: MN risk factors comprise three different clinical groups: psychosocial and lifestyle factors, laboratory findings and disease-associated factors. The patients who are most likely to be malnourished are those with valve pathology, severe imparted heart function, insufficient renal function and high inflammatory markers. Also these patients have decreased mobility and food intake.

Impact of malnutrition on postoperative delirium development after on pump coronary artery bypass grafting.

BACKGROUND & AIMS: Even though malnutrition is frequently observed in cardiac population outcome data after cardiac surgery in malnourished patients is very rare. No thorough research was done concerning the impact of malnutrition on neuropsychological outcomes after cardiac surgery. The aim of our study was to analyze the incidence of postoperative delirium development in malnourished patients undergoing on pump bypass grafting. METHODS: We performed a cohort study of adults admitted to Vilnius University Hospital Santariskiu Clinics for elective coronary artery bypass grafting. The nutritional status of the patients was assessed by Nutritional Risk Screening 2002 (NRS-2002) questionnaire the day before surgery. Patients were considered as having no risk of malnutrition when NRS-2002 score was less than 3 and at risk of malnutrition when NRS-2002 score was ≥3. During ICU stay patients were screened for postoperative delirium development using the CAM-ICU method. and divided into two groups: delirium and non delirium. The statistical analysis was preformed to evaluate the differences between the two independent groups. The logistic regression model was used to evaluate the potential preoperative and intraoperative risk factors of postoperative delirium. RESULTS: Ninety-nine patients were enrolled in the study. Preoperative risk of malnutrition was detected in 24 % (n = 24) of the patients. The incidence of early postoperative delirium in overall study population was 8.0 % (n = 8). The incidence of the patients at risk of malnutrition was significantly higher in the delirium group (5 (62.5 %) vs 19 (20.9 %), p <0.0191). In multivariate logistic regression analysis risk of malnutrition defined by NRS 2002 was an independent preoperative and intraoperative risk factor of postoperative delirium after coronary artery bypass grafting (OR: 6.316, 95 % CI: 1.384-28.819 p = 0.0173). CONCLUSIONS: Preoperative malnutrition is common in patients undergoing elective coronary artery bypass grafting. Nutrition deprivation is associated with early postoperative delirium after on pump coronary artery bypass grafting.

Incidence and risk factors of early delirium after cardiac surgery.

INTRODUCTION: The aim of our study was to identify the incidence and risk factors of delirium after cardiac surgery implementing Intensive Care Delirium Screening Checklist (ICDSC). MATERIAL AND METHODS: 87 patients, undergoing cardiac surgery at Vilnius University hospital, were prospectively monitored for postoperative delirium development, during intensive care unit stay. RESULTS: The incidence of postoperative delirium was 13.30%. No statistically relevant preoperative predictors of delirium were found. The duration of surgery was significantly longer in delirium group (4.51 ± 1.15 versus 3.76 ± 0.97 hours, P = 0.017). Patients in delirium group more often had blood product transfusions (1.50 (± 1.57) versus 0.49 (± 0.91) P = 0.003) and had a higher incidence of low cardiac output syndrome (33.30% versus 3.00%, P = 0.004); they were significantly longer mechanically ventilated (24.31 ± 28.35 versus 8.78 ± 4.77 (P < 0.001)) hours (OR = 1.15 (1.02-1.28)) and had twice longer ICU stay (5.00 ± 2.22 versus 2.60 ± 1.10 (P < 0.001)) days (OR = 1.91 (1.22-3.00)). CONCLUSIONS: The incidence of delirium after cardiac surgery was 13.3%. Independent predictors of delirium were duration of postoperative mechanical ventilation and intensive care unit stay.

Comparison of different anesthetic regimens in patients undergoing laparoscopic adjustable gastric banding operations: a prospective randomized trial.

BACKGROUND AND OBJECTIVE: Obesity is a multisystem disorder, particularly involving the respiratory and cardiovascular systems; therefore, a multidisciplinary approach is required. In spite of widespread performance of weight reduction (bariatric) surgeries, information regarding the anesthetic care of morbidly obese patients is scarce. The aim of this study was to compare the impact of fentanyl and remifentanil on the time of recovery, breathing parameters, and postoperative pain in morbidly obese patients undergoing laparoscopic adjustable gastric banding operations. MATERIAL AND METHODS: In this prospective randomized study, 66 morbidly obese patients (BMI>35 kg/m(2)), aged between 24 and 70 years, scheduled for a laparoscopic adjustable gastric banding operation were divided into 2 groups based on the opioid used for anesthesia: group 1 whose who received remifentanil; and group 2, fentanyl). The following parameters were recorded: peripheral blood oxygenation (SpO2) while breathing room air at baseline and 5 minutes after preoxygenation (100%); end-tidal carbon dioxide pressure at designated time points during the procedure; time to extubation; SpO2 in the postanesthesia care unit; and pain intensity (using the visual analogue scale); and the presence of nausea and vomiting. RESULTS: The time to extubation was shorter in the remifentanil group, but there was no significant difference in the time to discharge from the postanesthesia care unit. The recovery of respiratory parameters to the baseline values was better and faster in the remifentanil group. The intensity of postoperative pain was similar in both groups (VAS, <3) CONCLUSIONS: Remifentanil showed good analgesic properties during laparoscopic gastric banding surgery. Postanesthesia recovery and return of respiratory parameters to the baseline values was faster when remifentanil was used. Postoperative pain and the rate of opioid-induced side effects after analgesia with remifentanil were similar as after anesthesia with a longer acting opioid, fentanyl. Despite the problem widely discussed in literature about remifentanil-induced hyperalgesia, no cases of analgesic overconsumption were registered in our study.
