Jardot F, Hahn RG, Engel D, Beilstein CM, Wuethrich PY. Blood volume and hemodynamics during treatment of major hemorrhage with Ringer solution, 5% albumin, and 20% albumin: a single-center randomized controlled trial. Crit Care 2024; 28:39. [PMID: 38317178 PMCID: PMC10840277 DOI: 10.1186/s13054-024-04821-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Accepted: 01/28/2024] [Indexed: 02/07/2024] Open
Abstract
BACKGROUND Volume replacement with crystalloid fluid is the conventional treatment of hemorrhage. We challenged whether a standardized amount of 5% or 20% albumin could be a viable option to maintain the blood volume during surgery associated with major hemorrhage. Therefore, the aim of this study was to quantify and compare the plasma volume expansion properties of 5% albumin, 20% albumin, and Ringer-lactate, when infused during major surgery. METHODS In this single-center randomized controlled trial, fluid replacement therapy to combat hypovolemia during the hemorrhagic phase of cystectomy was randomly allocated in 42 patients to receive either 5% albumin (12 mL/kg) or 20% albumin (3 mL/kg) over 30 min at the beginning of the hemorrhagic phase, both completed by a Ringer-lactate replacing blood loss in a 1:1 ratio, or Ringer-lactate alone to replace blood loss in a 3:1 ratio. Measurements of blood hemoglobin over 5 h were used to estimate the effectiveness of each fluid to expand the blood volume using the following regression equation: blood loss plus blood volume expansion = factor + volume of infused albumin + volume of infused Ringer-lactate. RESULTS The median hemorrhage was 848 mL [IQR: 615-1145]. The regression equation showed that the Ringer-lactate solution expanded the plasma volume by 0.18 times the infused volume while the corresponding power of 5% and 20% albumin was 0.74 and 2.09, respectively. The Ringer-lactate only fluid program resulted in slight hypovolemia (mean, - 313 mL). The 5% and 20% albumin programs were more effective in filling the vascular system; this was evidenced by blood volume changes of only + 63 mL and - 44 mL, respectively, by long-lasting plasma volume expansion with median half time of 5.5 h and 4.8 h, respectively, and by an increase in the central venous pressure. CONCLUSION The power to expand the plasma volume was 4 and almost 12 times greater for 5% albumin and 20% albumin than for Ringer-lactate, and the effect was sustained over 5 h. The clinical efficacy of albumin during major hemorrhage was quite similar to previous studies with no hemorrhage.

Complications After Radical Cystectomy: A Systematic Review and Meta-analysis of Randomized Controlled Trials with a Meta-regression Analysis. Eur Urol Focus 2023; 9:920-929.

Abstract
CONTEXT Radical cystectomy is considered a procedure of high complexity with a relative high complication rate. OBJECTIVE To systematically summarize the literature regarding the complications of radical cystectomy and the factors that contribute to them. EVIDENCE ACQUISITION We searched MEDLINE/PubMed, ClinicalTrials.gov, and Cochrane Library, according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines for randomized controlled trials (RCTs) on complications related to radical cystectomy. EVIDENCE SYNTHESIS A total of 3766 studies were screened, and 44 studies were included in this systematic review and meta-analysis. Complications following radical cystectomy are quite common. The most common complications were gastrointestinal complications (20%), infectious complications (17%), and ileus (14%). The majority of complications occurring were Clavien I-II (45%). Specific measurable patient factors are related to certain complications and can be used to stratify risk and assist in preoperative counseling, while proper design of high-quality RCTs may better reflect real-life complication rates. CONCLUSIONS In our study, RCTs with a low risk of bias had higher complication rates than studies with a high risk of bias, underlining the need for further improvement on complication reporting in order to refine surgical outcomes. PATIENT SUMMARY Radical cystectomy is usually followed by high complication rates, which affect patients and are, in turn, strongly associated with patients' preoperative health status.

Impact of Intraoperative Fluid Balance and Norepinephrine on Postoperative Acute Kidney Injury after Cystectomy and Urinary Diversion over Two Decades: A Retrospective Observational Cohort Study. J Clin Med 2023; 12:4554. [PMID: 37445588 DOI: 10.3390/jcm12134554] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 07/04/2023] [Accepted: 07/05/2023] [Indexed: 07/15/2023] Open
Abstract
The use of norepinephrine and the restriction of intraoperative hydration have gained increasing acceptance over the last few decades. Recently, there have been concerns regarding the impact of this approach on renal function. The objective of this study was to examine the influence of norepinephrine, intraoperative fluid administration and their interaction on acute kidney injury (AKI) after cystectomy. In our cohort of 1488 consecutive patients scheduled for cystectomies and urinary diversions, the overall incidence of AKI was 21.6% (95%-CI: 19.6% to 23.8%) and increased by an average of 0.6% (95%-CI: 0.1% to 1.1%, p = 0.025) per year since 2000. The fluid and vasopressor regimes were characterized by an annual decrease in fluid balance (-0.24 mL·kg-1·h-1, 95%-CI: -0.26 to -0.22, p < 0.001) and an annual increase in the amount of norepinephrine of 0.002 µg·kg-1·min-1 (95%-CI: 0.0016 to 0.0024, p < 0.001). The interaction between the fluid balance and norepinephrine levels resulted in a U-shaped association with the risk of AKI; however, the magnitude and shape depended on the reference categories of confounders (age and BMI). We conclude that decreased intraoperative fluid balance combined with increased norepinephrine administration was associated with an increased risk of AKI. However, other potential drivers of the observed increase in AKI incidence need to be further investigated in the future.

Abstract
The aim of this study was to evaluate the feasibility of opioid-free anesthesia (OFA) in open radical cystectomy (ORC) with urinary diversion and to assess the impact on recovery of gastrointestinal function. We hypothesized that OFA would lead to earlier recovery of bowel function. A total of 44 patients who underwent standardized ORC were divided into two groups (OFA group vs. control group). In both groups, patients received epidural analgesia (OFA group: bupivacaine 0.25%, control group: bupivacaine 0.1%, fentanyl 2 mcg/mL, and epinephrine 2 mcg/mL). The primary endpoint was time to first defecation. Secondary endpoints were incidence of postoperative ileus (POI) and incidence of postoperative nausea and vomiting (PONV). The median time to first defecation was 62.5 h [45.8-80.8] in the OFA group and 118.5 h [82.6-142.3] (p < 0.001) in the control group. With regard to POI (OFA group: 1/22 patients (4.5%); control group: 2/22 (9.1%)) and PONV (OFA group: 5/22 patients (22.7%); control group: 10/22 (45.5%)), trends but no significant results were found (p = 0.99 and p = 0.203, respectively). OFA appears to be feasible in ORC and to improve postoperative functional gastrointestinal recovery by halving the time to first defecation compared with standard fentanyl-based intraoperative anesthesia.

Perioperative continuation of aspirin, oral anticoagulants or bridging with therapeutic low-molecular-weight heparin does not increase intraoperative blood loss and blood transfusion rate in cystectomy patients: an observational cohort study. BJU Int 2022; 129:512-523.

Abstract
OBJECTIVE To assess if uninterrupted anticoagulant agents' administration affects blood loss and blood transfusion during open radical cystectomy (RC) and urinary diversion. PATIENTS AND METHODS We conducted an observational single-centre cohort study of a consecutive series of 1430 RC patients, between 2000 and 2020. Blood loss was depicted according to body weight and duration of surgery (mL/kg/h), and blood transfusion. The group 'with anticoagulant agents' was considered if surgery was performed with uninterrupted low-dose aspirin (ASS), oral anticoagulants (OAC) with an international normalised ratio (INR) goal of 2-2.5 or bridging with therapeutic low-molecular-weight heparin (LMWH). Outcomes were intraoperative blood loss, blood transfusion rate (separately analysed if administered within 24 h perioperatively or >24 h after surgery) and the 90-day major adverse cardiac events (MACE) rate. We used propensity score (PS)-matching analysis to adjust for imbalances between groups with or without anticoagulant agents. RESULTS The PS-matched median (interquartile range [IQR]) blood loss was 2.10 (1.50-2.94) mL/kg/h in patients with anticoagulant agents vs 2.11 (1.47-2.94) mL/kg/h without anticoagulant agents (Padj > 0.99). The PS-matched blood transfusion rates were 26.2% vs 35.1% (Padj = 0.875) within 24 h perioperatively and 57.0% vs 55.0% (Padj = 0.680) if administered >24 h postoperatively. A sub-analysis of the three different anticoagulant agents could not detect any significance between ASS, OAC, or LMWH. The PS-matched incidence of MACE was 9.1% in the group with anticoagulant agents and 8.1% in those without anticoagulant agents (Padj > 0.99). Limitations include selection bias and retrospective analysis from prospectively assessed data. CONCLUSIONS Perioperative continuation of ASS, uninterrupted OAC with low INR goal or bridging with LMWH had no impact on blood loss and transfusion rate in RC patients. Therefore, there might be no compulsory need for discontinuation of anticoagulant agents.

Abstract
Preoperative dehydration is usually found in 30–50% of surgical patients, but the incidence is unknown in the urologic population. We determined the prevalence of preoperative dehydration in major elective urological surgery and studied its association with postoperative outcome, with special attention to plasma creatinine changes. We recruited 187 patients scheduled for major abdominal urological surgery to participate in a single-center study that used the fluid retention index (FRI), which is a composite index of four urinary biomarkers that correlate with renal water conservation, to assess the presence of dehydration. Secondary outcomes were postoperative nausea and vomiting (PONV), return of gastrointestinal function, in-hospital complications, quality of recovery, and plasma creatinine. The proportion of dehydrated patients at surgery was 20.4%. Dehydration did not correlate with quality of recovery, PONV, or other complications, but dehydrated patients showed later defecation (p = 0.02) and significant elevations of plasma creatinine after surgery. The elevations were also greater when plasma creatinine had increased rather than decreased during the 24 h prior to surgery (p < 0.001). Overall, the increase in plasma creatinine at 6 h after surgery correlated well with elevations on postoperative days one and two. In conclusion, we found preoperative dehydration in one-fifth of the patients. Dehydration was associated with delayed defecation and elevated postoperative plasma creatinine. The preoperative plasma creatinine pattern could independently forecast more pronounced increases during the early postoperative period.

Abstract
BACKGROUND The intraoperative effect of 20% albumin on plasma volume during surgery involving major blood loss has not been explored extensively due to methodological difficulties. Crystalloids poorly expand the plasma volume, and using a colloid might then be a way to avoid fluid overload. As doubts have been raised about synthetic colloids, albumin solutions are currently used more extensively. This study presents a methodological development showing how plasma volume expansion can be studied in surgical settings with the coinfusion of 20% albumin and lactated Ringer's solution. METHODS In this single-arm, single-center feasibility study, an intravenous (i.v.) infusion of 3 mL·kg·BW-1 of 20% albumin was administered over 30 minutes to 23 cystectomy patients during the bleeding phase in addition to lactated Ringer's solution to correct blood loss. Blood samples were measured at regular intervals over a period of 300 minutes to estimate the blood volume expansion resulting from simultaneous infusions of lactated Ringer's and 20% albumin solutions, using a regression equation and the area under the volume-time curve method. RESULTS Mean hemorrhage was 974 mL (standard deviation [SD] ± 381). The regression method showed strong correlation (r2 = 0.58) between blood loss minus blood volume expansion and the independent effects of the infused volume of lactated Ringer's and 20% albumin solutions. The mean plasma volume expansion attributable to the infusion of lactated Ringer's solution amounted to 0.38 (95% confidence interval [CI], 0.31-0.49) of the infused volume; for the 20% albumin, it was 1.94 mL/mL (95% CI, 1.41-2.46 mL/mL) over 5 hours on average (regression method). The mean within-patient change was 0.20 mL/mL (± 0.06 mL/mL) for the lactated Ringer's solution and 2.20 mL/mL (±1.31 mL/mL) for the 20% albumin using the area under the volume-time curve method. CONCLUSIONS Blood volume expansion averaged 1.9-2.2 times the infused volume of 20% albumin during surgery associated with hemorrhage of around 1000 mL. This effect was long standing and approximately 5 times stronger than for the lactated Ringer's solution. Twenty percent albumin boosts the plasma volume expansion of lactated Ringer's solution to as high as 40% of the infused volume on the average, which is an effect that lasts at least 5 hours.

Abstract
BACKGROUND The impact of anaesthetic techniques on recurrence of cancers is controversial. Elevated plasma catecholamine levels have been implicated in angiogenesis and metastasis in various cancers. OBJECTIVES To assess the potential association between continuous intra-operative norepinephrine administration and tumour-related outcome in muscle-invasive bladder cancer patients undergoing radical cystectomy with urinary diversion. DESIGN Retrospective observational cohort study. SETTING Single tertiary centre, from 2000 to 2017. PATIENTS We included a consecutive series of 1120 urothelial carcinoma patients undergoing radical cystectomy and urinary diversion, including 411/1120 patients (37%) who received a continuous intra-operative administration of more than 2 μg kg BW h norepinephrine. MAIN OUTCOME MEASURES The primary outcome was time to tumour recurrence within 5 years after surgery, with death as competing outcome. We used inverse probability of treatment weighting to adjust for imbalances between treatment groups, one having received more than 2 μg kg BW h norepinephrine and the other having received less. We furthermore adjusted for intra-operative variables or years of surgery as sensitivity analyses. RESULTS The continuous administration of more than 2 μg kg BW h norepinephrine slightly increased tumour recurrence (hazard ratio: 1.47, 95% CI 0.98 to 2.21; P = 0.061). After adjustment for intra-operative variables, and year of surgery hazard ratios were 1.82 (95% CI 1.13 to 2.91, P = 0.013) and 1.85 (95% CI 1.12 to 3.07, P = 0.017), respectively. Overall mortality (with or without tumour recurrence) was not affected by norepinephrine (hazard ratio: 0.84, 95% CI 0.65 to 1.08, P = 0.170). CONCLUSION Continuous administration of more than 2 μg kg BW h norepinephrine was associated with a slightly increased hazard ratio for tumour recurrence if adjusted for intra-operative variables and year of surgery. This observation could reflect a low potential pro-oncogenic effect of norepinephrine during the intra-operative period. TRIAL REGISTRATION Not applicable.

Abstract
BACKGROUND The use of noradrenaline to enable a restrictive approach to intra-operative fluid therapy to avoid salt and water overload has gained increasing acceptance. However, concerns have been raised about the impact of this approach on renal function. OBJECTIVES To identify risk factors for acute kidney injury (AKI) in patients undergoing cystectomy with urinary diversion and determine whether administration of noradrenaline and intra-operative hydration regimens affect early postoperative renal function. DESIGN Retrospective observational cohort study. SETTING University hospital, from 2007 to 2016. PATIENTS A total of 769 consecutive patients scheduled for cystectomy and urinary diversion. Those with incomplete data and having pre-operative haemodialysis were excluded. MAIN OUTCOME MEASURES AKI was defined as a serum creatinine increase of more than 50% over 72 postoperative hours. Multiple logistic regression analysis was performed to model the association between risk factors and AKI. RESULTS Postoperative AKI was diagnosed in 86/769 patients (11.1%). Independent predictors for AKI were the amount of crystalloid administered (odds ratio (OR) 0.79 [95% confidence interval (CI), 0.68 to 0.91], P = 0.002), antihypertensive medication (OR 2.07 [95% CI, 1.25 to 3.43], P = 0.005), pre-operative haemoglobin value (OR 1.02 [95% CI, 1.01 to 1.03], P = 0.010), duration of surgery (OR 1.01 [95% CI, 1.00 to 1.01], P = 0.002), age (OR 1.32 [95% CI, 1.44 to 1.79], P = 0.002) but not the administration of noradrenaline (OR 1.09 [95% CI, 0.94 to 1.21], P = 0.097). Postoperative AKI was associated with longer hospital stay (18 [15 to 22] vs. 16 [15 to 19] days; P = 0.035) and a higher 90-day major postoperative complication rate (41.9 vs. 27.5%; P = 0.002). CONCLUSION Noradrenaline administration did not increase the risk for AKI. A too restrictive approach to administration of crystalloids was associated with an increased risk for AKI, particularly in older patients, those receiving antihypertensive medication, and those whose surgery was prolonged. As AKI was associated with longer hospital stay and increased postoperative morbidity, these observations should be taken into account to improve outcome when addressing peri-operative fluid management.

Abstract
PURPOSE The aim of this review is to present an anesthesiological overview on surgical safety for radical cystectomy implementing the cornerstones of today's rapidly evolving field of perioperative medicine. METHODS This is a narrative review of current perioperative medicine and surgical safety concepts for major surgery in general with special focus on radical cystectomy. RESULTS The tendency for perioperative care and surgical safety is to consider it a continuous proactive pathway rather than a single surgical intervention. It starts at indication for surgery and lasts until full functional recovery. Preoperative optimization leads to superior outcome by mobilizing and/or increasing physiological reserve. Multidisciplinary teamwork involving all the relevant parties from the beginning of the pathway is crucial for outcome rather than an isolated specialist approach. This fact has gained importance in times of an ageing frail population and rising health care cost. We also present our 2019 Cystectomy Enhanced Recovery Approach for optimization of perioperative care for open radical cystectomy in a high caseload center. CONCLUSIONS With the implementation of in itself simple but crucial steps in perioperative medicine such as multimodal prehabilitation, safety checks, better perioperative monitoring and enhanced recovery concepts, even complex surgical procedures such as radical cystectomy can be performed safer. Emphasis has to be laid on a more global view of the patients' path through the perioperative process than on the surgical procedure alone.

Abstract
Abstract
Background
Gastrointestinal (GI) complications often delay recovery after radical cystectomy with urinary diversion. The authors investigated if perioperative administration of a potassium-enriched, chloride-depleted 5% glucose solution (G5K) accelerates recovery of GI function.
Methods
This randomized, parallel-group, single-center double-blind trial included 44 consecutive patients undergoing radical cystectomy and pelvic lymph node dissection with urinary diversion. Patients were randomized to receive either a G5K (G5K group) solution or a Ringer’s maleate solution (control group). Fluid management aimed for a zero fluid balance. Primary endpoint was time to first defecation. Secondary endpoints were time to normal GI function, need for electrolyte substitution, and renal dysfunction.
Results
Time to first defecation was not significantly different between groups (G5K group, 93 h [19 to 168 h] and control group, 120 h [43 to 241 h]); estimator of the group difference, −16 (95% CI, −38 to 6); P = 0.173. Return of normal GI function occurred faster in the G5K group than in the control group (median, 138 h [range, 54 to 262 h] vs. 169 h [108 to 318 h]); estimator of the group difference, −38 (95% CI, −74 to −12); P = 0.004. Potassium and magnesium were less frequently substituted in the G5K group (13.6 vs. 54.5% [P = 0.010] and 18.2 vs. 77.3% [P < 0.001]), respectively. The incidence of renal dysfunction (Risk, Injury, Failure, Loss and End-stage kidney disease stage “risk”) at discharge was 9.1% in the G5K group and 4.5% in the control group; P = 1.000.
Conclusions
Perioperative administration of a G5K did not enhance first defecation, but may accelerate recovery of normal GI function, and reduces potassium and magnesium substitution after radical cystectomy and urinary diversion.
