Objective: To observe the effect of modified ultrafiltration on hemodynamics of pediatric patients. Study Design: A descriptive cross-sectional study. Place and Duration of Study: Pediatric Cardiac Surgery department, AFIC/NIHD Rawalpindi, from Jun 2019 to Dec 2019. Methodology: A total of 60 pediatric patients were included undergoing open-heart surgery with cardiopulmonary bypass, having age ≤6 years and weights ≤15kg. To assess hemodynamics parameters observed were pre modified ultrafiltration and post modified ultrafiltration measurements of haemoglobin level, systolic pressure, diastolic pressure, central venous pressure and the number of transfusions given after off-bypass. The data was entered and analyzed in SPSS-23. Results: The pre-operative mean Hb level of the 60 sampled patients was 12.08 ± 2.89 g/dl. The findings taken pre modified ultrafiltration and post modified ultrafiltration of haemoglobin level was (9.91 ± 0.91 g/dl and 13.09 ± 1.38 g/dl, p<0.05) after an average filtration of 370.83 ± 66.56 ml of the filtrate. The mean of systolic pressure was (61.3 ± 2.01 mmHg and 70.68 ± 1.76 mmHg, p<0.05), diastolic pressure was (49.95 ± 1.35 and 59.7 ± 6.85, p<0.005), Central Venous Pressure was (10.07 ± 1.18 and 9.9 ± 1.09, p>0.005) compared pre modified ultrafiltration and post modified ultrafiltration respectively. Conclusion: The study concluded that modified ultrafiltration has a significant impact on haemoglobin levels after bypass, decreases the allogenic transfusions and also improve the hemodynamics of the patient.

Clinical Cases

We devised a new method and system for the automatic regulation of cardiopulmonary bypass. The system is planned so that it is regulated according to the alteration of venous pressure which is a reflection of venous return in total cardiopulmonary bypass. After many experimental studies, we have used this system in four clinical cases of cardiac surgery. The system functioned sufficiently well in the clinical cases. Under the control of this system, the central venous pressure was kept at a preset level and changed cyclically in the same manner as the respiratory change through the entire cardiopulmonary bypass period. A constant and adequate venous return through the entire cardiopulmonary bypass period was assumed to be the most important factor for the venous return-triggered pump oxygenator.

Abstract Background We aimed to investigate the relationship between the perioperative hemodynamic parameters and the occurrence of cardiac surgery-associated acute kidney injury. Methods A retrospective study was performed in patients underwent cardiac surgery at a tertiary referral teaching hospital. Acute kidney injury was determined according to the KDIGO criteria. We investigated the association between the following perioperative hemodynamic parameters and cardiac surgery-associated acute kidney injury: mean arterial pressure, mean perfusion pressure, central venous pressure, and diastolic perfusion pressure. Multivariate regression analysis was conducted to identify the independent hemodynamic predictors for the development of acute kidney injury. Subgroup analysis was further performed in patients with chronic hypertension. Results Among 300 patients, 29.3% developed acute kidney injury during postoperative intensive care unit period. Multivariate logistic analysis showed the postoperative nadir diastolic perfusion pressure, but not mean arterial pressure, central venous pressure and mean perfusion pressure, was independently linked to the development of acute kidney injury after cardiac surgery (odds ratio 0.945, P = 0.045). Subgroup analyses in hypertensive subjects showed the postoperative nadir diastolic perfusion pressure and peak central venous pressure were both independently related to the development of acute kidney injury (nadir diastolic perfusion pressure, odds ratio 0.886, P = 0.033; peak central venous pressure, odds ratio 1.328, P = 0.010, respectively). Conclusions Postoperative nadir diastolic perfusion pressure was independently associated with the development of cardiac surgery-associated acute kidney injury. Furthermore, central venous pressure should be considered as a potential hemodynamic target for hypertensive patients undergoing cardiac surgery.

The Impact

Background: Cardiac surgery patients represent a high-risk cohort in intensive care units (ICUs). Central venous pressure (CVP) measurement seems to remain an integral part in hemodynamic monitoring, especially in cardio-surgical ICUs. However, its value as a prognostic marker for organ failure is still unclear. Therefore, we analyzed postoperative CVP values after adult cardiac surgery in a large cohort with regard to its prognostic value for morbidity and mortality. Methods: All adult patients admitted to our ICUs between 2006 and 2019 after cardiac surgery were eligible for inclusion in the study (n = 11,198). We calculated the median initial CVP (miCVP) after admission to the ICU, which returned valid values for 9802 patients. An ROC curve analysis for optimal cut-off miCVP to predict ICU mortality was conducted with consecutive patient allocation into a (a) low miCVP (LCVP) group (≤11 mmHg) and (b) high miCVP (HCVP) group (>11 mmHg). We analyzed the impact of high miCVP on morbidity and mortality by propensity score matching (PSM) and logistic regression. Results: ICU mortality was increased in HCVP patients. In addition, patients in the HCVP group required longer mechanical ventilation, had a higher incidence of acute kidney injury, were more frequently treated with renal replacement therapy, and showed a higher risk for postoperative liver dysfunction, parametrized by a postoperative rise of ≥ 10 in MELD Score. Multiple regression analysis confirmed HCVP has an effect on postoperative ICU-mortality and intrahospital mortality, which seems to be independent. Conclusions: A high initial CVP in the early postoperative ICU course after cardiac surgery is associated with worse patient outcome. Whether or not CVP, as a readily and constantly available hemodynamic parameter, should promote clinical efforts regarding diagnostics and/or treatment, warrants further investigations.
