Background. Surgical stress during major surgery may be related to adverse clinical outcomes and early quantification of stress response would be useful to allow prompt interventions. The aim of this study was to evaluate the acute phase protein albumin in the context of the postoperative stress response.Methods. This prospective pilot study included 70 patients undergoing frequent abdominal procedures of different magnitude. Albumin (Alb) and C-reactive protein (CRP) levels were measured once daily starting the day before surgery until postoperative day (POD) 5. Maximal Alb decrease (Alb Δ min) was correlated with clinical parameters of surgical stress, postoperative complications, and length of stay.Results. Albumin values dropped immediately after surgery by about 10 g/L (42.2±4.5 g/L preoperativelyversus33.8±5.3 g/L at day 1,P<0.001). Alb Δ min was correlated with operation length (Pearsonρ=0.470,P<0.001), estimated blood loss (ρ=0.605,P<0.001), and maximal CRP values (ρ=0.391,P=0.002). Alb Δ min levels were significantly higher in patients having complications (10.0±5.4versus6.1±5.2,P=0.005) and a longer hospital stay (ρ=0.285,P<0.020).Conclusion. Early postoperative albumin drop appeared to reflect the magnitude of surgical trauma and was correlated with adverse clinical outcomes. Its promising role as early marker for stress response deserves further prospective evaluation.

Despite the significant advances made by modern anesthesiology in the perioperative management of patients, surgical interventions are still accompanied by a high proportion of complications and even deaths. At the same time, it is known that in 50% of cases mortality and serious postoperative complications could be prevented. After performing a thorough study of the factors affecting the increase in hospitalization and postoperative recovery (Kehlet H., 1997; Kehlet H., Wilmore D., 2002), it was determined that the surgical stress response is the most significant inducer of dysfunction of various organs. and systems. To date, it has been established that general anesthesia in its classical sense does not allow achieving complete protection of the patient from surgical trauma. More complete protection can be achieved by combining general anesthesia with regional blockages and adjuvant drugs with stress-protective properties. In the present study, we compared the severity of the surgical stress response and pain syndrome in patients operated on under conditions of multicomponent balanced general anesthesia (group K) with patients who received a stress-limiting anesthesia regimen (group DB). In both groups, multicomponent anesthesia was performed, in group K, sibazone was used for sedation, in group DB, dexmedetomidine was used. Also, patients of the DB group underwent regional blockade (blockade of the pterygo-palatine fossa) before surgery. The main criteria for evaluating the results were: hemodynamic stability, blood glucose, the level of venous blood leukocytes and the severity of pain according to the VAS in the postoperative period. Both schemes made it possible to avoid pronounced fluctuations in hemodynamic and gas exchange parameters at all stages of the study. When analyzing blood glucose and leukocyte counts, it was found that patients in the control group had a more significant deviation of both indicators from the preoperative level than in the stress-limiting anesthesia group. In the study of pain syndrome, it was determined that in the control group the level of pain according to the VAS was higher at all stages of the study compared to patients in the group of stress-limiting anesthesia.

Muscle protein catabolism is a considerable clinical problem following surgery. However, the impact of surgical trauma on muscle protein synthesis is not well characterized. In this pilot study, we therefore investigated whether the severity of surgical trauma is related to a decrease in muscle protein synthesis rate in humans. Metabolically healthy patients (n=28) were included in the study. Eight of the patients were day-care patients undergoing minor breast surgery (defined as minor surgery). The other 20 patients were subjected to major abdominal surgery and were therefore scheduled to stay overnight in the recovery room during the first postoperative night (defined as major surgery). Protein FSRs (fractional synthesis rates) in skeletal muscle were determined during a measurement period of 90 min before surgery and immediately after termination of surgery. FSR in skeletal muscle of the minor surgery patients was 1.72±0.25%/24 h before surgery and 1.67±0.29%/24 h after surgery (P=0.68). In the major surgery group, FSR was 1.62±0.30%/24 h before surgery and 1.57±0.40%/24 h (P=0.59) immediately following surgery. The observations made in this pilot study could not confirm a size-related decrease in muscle protein synthesis immediately following minor and major surgery. This finding is discussed in relation to confounders, postoperative course and to muscle protein degradation. The shortage of knowledge in this field is emphasized.

SummaryTen patients for elective cholecystectomy were studied pre-, per- and postoperatively. All had neurolept anesthesia. Plasma concentrations of β-TG, TXB2 and 5-HT and intraplatelet 5-HT were measured. Aggregation to ADP was recorded.Serum cortisol concentration was used as index of the stress response, showing peroperative increase and postoperative decrease. Closely related to this we observed a significant increase in P-β-TG and P-TXB2 with postoperative normalization in 6 patients without complications. P-5-HT had a peak peropera-tively and remained elevated postoperatively. A negative correlation between P--5-HT and decreasing intraplatelet 5-HT postoperatively was observed.High postoperative levels of P--5-HT seem to be related to low arterial Po2 and pulmonary dysfunction. In 3 patients with complications a second increase in P-β-TG, P-TXB2 and partly in P--5-HT was found. Platelets were temporarily refractory to ADP immediately following surgery and showed increased aggregabil-ity postoperatively. We conclude that platelets are activated in surgical stress.

Abstract Background The clinical and economic impacts of enhanced recovery after surgery (ERAS) programmes have been demonstrated extensively. Whether ERAS protocols also have a biological effect remains unclear. This study aimed to investigate the biological impact of an ERAS programme in patients undergoing liver surgery. Methods A retrospective analysis of patients undergoing liver surgery (2010–2018) was undertaken. Patients operated before and after ERAS implementation in 2013 were compared. Surrogate markers of surgical stress were monitored: white blood cell count (WBC), C-reactive protein (CRP) level, albumin concentration, and haematocrit. Their perioperative fluctuations were defined as Δvalues, calculated on postoperative day (POD) 0 for Δalbumin and Δhaematocrit and POD 2 for ΔWBC and ΔCRP. Results A total of 541 patients were included, with 223 and 318 patients in non-ERAS and ERAS groups respectively. Groups were comparable, except for higher rates of laparoscopy (24.8 versus 11.2 per cent; P &lt; 0.001) and major resection (47.5 versus 38.1 per cent; P = 0.035) in the ERAS group. Patients in the ERAS group showed attenuated ΔWBC (2.00 versus 2.75 g/l; P = 0.013), ΔCRP (60 versus 101 mg/l; P &lt;0.001) and Δalbumin (12 versus 16 g/l; P &lt; 0.001) compared with those in the no-ERAS group. Subgroup analysis of open resection showed similar results. Multivariable analysis identified ERAS as the only independent factor associated with high ΔWBC (odds ratio (OR) 0.65, 95 per cent c.i. 0.43 to 0.98; P = 0.038), ΔCRP (OR 0.41, 0.23 to 0.73; P = 0.003) and Δalbumin (OR 0.40, 95 per cent c.i. 0.22 to 0.72; P = 0.002). Conclusion Compared with conventional management, implementation of ERAS was associated with an attenuated stress response in patients undergoing liver surgery.

Background and Objectives: On 24 March 2020, the United States Food and Drug Administration (FDA) announced the approval of convalescent plasma therapy for critically ill patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as an emergency investigational new drug. This pilot study from Romania aimed to determine if convalescent plasma transfusion can be beneficial in the treatment of selected critically ill patients diagnosed with a SARS-CoV-2 infection. Materials and Methods: Donor and receiver eligibility for critically ill coronavirus disease 2019 (COVID-19) patients was based on Romanian guidelines issued at the time of the study. Here, we describe the evolution of a total of five eligible patients diagnosed with COVID-19 who received convalescent plasma (CP) in Romania. Results: In spite of our efforts and convalescent plasma administration, three of the five patients did not survive, while the other two recovered completely. Over the course of our five-day laboratory record, the surviving patients had significantly lower values for C-reactive protein, interleukin-6, and white blood cells. Conclusions: This pilot study provides insufficient evidence to determine the efficacy of convalescent plasma use as a therapeutic option for critically ill COVID-19 patients.
