Critical care management and intensive care unit outcomes following cytoreductive surgery with hyperthermic intraperitoneal chemotherapy

Profile of haemostasis and coagulation in patients with peritoneal carcinomatosis undergoing cytoreductive surgery with hyperthermal chemotherapy

BACKGROUND

One-third of patients with peritoneal carcinomatosis undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) present alterations in conventional coagulation test results. However, perioperative coagulation has not been systematically investigated in these patients. This study aimed to investigate hemostatic changes in such patients.

METHODS

This prospective observational study included patients with peritoneal carcinomatosis who underwent CRS-HIPEC. Variables of conventional coagulation and rotational thromboelastometry (ROTEM) parameters of patients who underwent CRS-HIPEC at baseline (time 0, T0: before surgery) were compared with those of healthy blood donors (HBD). Blood samples were collected at baseline (T0), 2-h (T2), and 72-h (T72) after surgery.

RESULTS

44 patients who underwent CRS-HIPEC and 40 HBDs were included. At T0, patients who underwent CRS-HIPEC presented with lower hemoglobin levels and elevated C-reactive protein, fibrinogen, factor XIII (FXIII), and D-dimer levels than HBDs. At T2, significant decreases in hemoglobin, platelet count, fibrinogen, and FXIII levels were observed. In contrast, D-dimer and von Willebrand factor levels increased. Regarding ROTEM parameters, in the postoperative period, increased clotting time in thromboelastometry with extrinsic activation, and maximum clot firmness in thromboelastometry with fibrin contribution, along with a significant decrease in maximum clot firmness in thromboelastometry with extrinsic activation without a hyperfibrinolysis pattern, were observed. Platelet function, as assessed using the platelet function assay, was normal.

CONCLUSIONS

CRS-HIPEC causes coagulopathy secondary to a pronounced platelet drop, worsening of fibrinogen and FXIII levels, and impaired clot firmness as evidenced by ROTEM. A proinflammatory status was ubiquitously observed.

Nursing care for cytoreduction and hyperthermic intraoperative chemotherapy in an Intensive Care Unit: a scoping review

OBJECTIVE

To map postoperative nursing care for critically ill adult and older patients admitted to the Intensive Care Unit after cytoreduction surgery with hyperthermic intraoperative intraperitoneal chemotherapy.

METHOD

TScoping review according to the JBI methodology, with articles extracted from databases and gray literature, with no language or publica-tion date delimitation. The studies selection and results extraction process was carried out by two independent reviewers, using the soft-ware EndNote® and Rayyan®. PRISMA Extension for Scoping Review was used for the writing, with registration on the Open Science Framework.

RESULTS

Forty-two studies were selected. The analysis revealed 72 types of care grouped into 14 care areas. The use of an epidural catheter for anal-gesia, optimization of individualized hemodynamic status, and strict control of fluid balance were the most cited care measures.

CONCLUSION

The mapping identified post-operative nursing care similar to those for major surgeries for patients recovering in the Intensive Care Unit, with an indication of the use of personal protective equipment by professionals when handling tubes in the first 48 hours of admission.

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy: Effects of postoperative fluids beyond the first 24 h

BACKGROUND AND OBJECTIVES

There are no guidelines for intravenous fluid (IVF) administration after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). This study assessed rates of post-CRS/HIPEC morbidity according to perioperative IVF administration.

METHODS

All patients undergoing CRS/HIPEC March 2007 to June 2018 were reviewed, recording clinicopathologic, operative, and postoperative variables. Patients were divided by peritoneal cancer index (PCI), comparing IVF volumes and types administered intraoperatively and during the first 72 h postoperatively. Optimal IVF rate cutoffs calculated using area under the receiver operating characteristic curves and Youden's index determined associations with complications.

RESULTS

Overall, 185 patients underwent CRS/HIPEC, and 81 (51%) had low PCI (<10) and 77 (49%) had high PCI (≥10). In low-PCI patients, high IVF rates on postoperative days (POD) #0-2 were associated with higher overall complications: POD#0 (46% vs. 89%, p = 0.001), POD#1 (40% vs. 86%, p < 0.05), and POD#2 (42% vs. 72%, p < 0.05). High IVF rates were associated with respiratory distress (7% vs. 26%, p = 0.02) on POD#0, ileus (14% vs. 47%, p = 0.007) and intensive care unit stay (11% vs. 33%, p = 0.022) on POD#1, and ICU stay (8% vs. 33%, p = 0.003) on POD#2.

CONCLUSIONS

For low PCI patients undergoing CRS/HIPEC, higher IVF rates were associated with postoperative complications. Post-CRS/HIPEC, IVF rates should be limited to prevent morbidity.

Is routine admission to a critical care setting following hyperthermic intraperitoneal chemotherapy for ovarian cancer necessary?

INTRODUCTION

Hyperthermic intraperitoneal chemotherapy (HIPEC) is increasingly being used in patients with stage III ovarian cancer undergoing interval cytoreductive surgery (CRS). It is uncertain whether routine postoperative admission to a critical care setting after CRS-HIPEC is necessary. This study aims to estimate the incidence of patients requiring critical care, and to create a prediction model to identify patients who may forego admission to a critical care setting.

METHODS

We analyzed 154 patients with primary ovarian cancer undergoing interval CRS-HIPEC at two Dutch centers between 2007 and 2021. Patients were routinely admitted to a critical care setting for 12-24 h. Patients that received critical support as defined by pre-specified definitions were retrospectively identified. Logistic regression analysis with backward selection was used to predict the need for critical care and the model was validated using bootstrapping.

RESULTS

Thirty-eight percent of patients received postoperative critical care, consisting mainly of hemodynamic interventions. Independent predictors of critical care were blood loss, norepinephrine dose during surgery, and age (bootstrapped AUC = 0.76). Using a probability cut-off of 20%, one-third of patients are defined as low-risk for requiring critical care, with a negative predictive value of 0.88.

CONCLUSIONS

The majority of patients,primarily undergoing low to intermediate complexity surgeries, did not receive critical care interventions after CRS-HIPEC. Selective admission to a critical care setting may be warranted and its feasibility and safety needs to be evaluated prospectively. Our prediction model can help identify patients in whom admission to a critical care setting may be omitted. Hospital costs and burden on critical care units will benefit from patient selection.

Vasopressors to treat postoperative hypotension after adult noncardiac, non-obstetric surgery: a systematic review

BACKGROUND

Postoperative hypotension is common after major surgery and is associated with patient harm. Vasopressors are commonly used to treat hypotension without clear evidence of benefit. We conducted a systematic review to better understand the use, impact, and rationale for vasopressor administration after noncardiac, non-obstetric surgery in adults.

METHODS

We conducted a prospectively registered systematic review. Cochrane CENTRAL, EMBASE, MEDBASE, and MEDLINE were searched for RCTs and cohort studies of adult patients receiving vasopressors after noncardiac, non-obstetric surgery. Study quality was critically appraised by two investigators. Findings from the review were synthesised, but formal meta-analysis was not performed because of significant variability in study populations and outcomes.

RESULTS

A total of 3201 articles were screened, of which seven RCTs, two prospective cohort studies, and 15 retrospective cohort studies were included in the analysis (24 in total). One study was graded as high quality, two as moderate quality, and the remaining 21 as low quality. Sixteen studies relied on clinical assessment alone to decide on therapeutic interventions. Vasodilation was the most common suggested physiological disturbance. The median proportion of patients receiving vasopressors was 42% (interquartile range: 11.5-74.7%). Norepinephrine was the most common vasopressor used.

CONCLUSIONS

The evidence supporting the use of vasopressors to treat postoperative hypotension is limited. Future research should focus on whether vasodilatation or other physiological disturbance is driving postoperative hypotension to allow rational decision-making.

Is There a Role for Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy in Peritoneal Carcinomatosis Due to Uterine Cancer?

BACKGROUND

Uterine canceris one of the most common pelvic tumors in females. Advanced stage uterine cancer only represents 15% of newly diagnosed cases; however, they are related with poor prognosis. Our aim was to analyze the benefits of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in peritoneal carcinomatosis due to uterine cancer.

METHODS

At the Istanbul Umraniye Training and Research Hospital, Surgical Oncology Clinic, morbidity, overall survival and survival without progression were analyzed over the 5-year follow up. Twenty-two cases who had undergone cytoreductive surgery and hyperthermic intraperitoneal chemotherapy due to uterine-peritoneal carcinomatosis were included in this study. Cases were followed up in terms of postoperative morbidity-mortality, disease-free survival and overall survival. The cut off value for the peritoneal carcinomatosis index score was set at 15. Intraperitoneal chemotherapy consisting of cisplatin and doxorubicin was applied to all patients for 60 min after the suturation of the abdomen.

RESULTS

Median age of the patients was 64.6 (43-72). Average PCI score was 12.8 (3-15). CC score was 0 in 16 (72.7%) cases, 1 in 3 cases and 2 in 3 cases. Of these patients, 12 of them were previously operated upon. Median stay at the hospital was 13.1 days. No major complications due to chemotherapy were reported. A Clavien-Dindo Grade 3 complication was observed in seven (31.8%) patients. Mortality was not observed in patients during their stay at the hospital. The 5-year disease-free survival and overall survival rates were 36.8 (36%) months and 45.3 (57%) months, respectively.

CONCLUSIONS

We think that due to longer disease-free survival and overall survival, cytoreductive surgery and hyperthermic intraperitoneal chemotherapy should be preferred in peritoneal carcinomatosis due to uterine cancer patients having low peritoneal carcinomatosis index scores and manageable complication rates. However, prospective randomizedtrials with a high number of cases are needed for this subject.

Perioperative anaesthetic management in cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC): a retrospective analysis in a single tertiary care cancer centre

OBJECTIVES

Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is associated with increased morbidity and mortality. We retrospectively analysed the perioperative anesthetic management in patients undergoing HIPEC surgery.

METHODS

After ethics approval, we reviewed the records of patients who underwent CRS/HIPEC from 2015 until 2020. We noted the peritoneal carcinomatosis index (PCI), blood loss, anastomoses done, total amount of fluid given, delta temperature and duration of surgery. These were correlated with the need for postoperative ventilation, length of ICU stay, Clavien-Dindo score and 30 day mortality.

RESULTS

Of the 180 patients reviewed, the majority were women (85%) with a mean age of 48 years who had ovarian tumors (n=114). The total amount of fluid given was associated with an increased length of ICU stay (p=0.008). Prolonged surgery resulted in increased length of ICU stay (p<0.001), need for postoperative ventilation (p=0.006) and a poor Clavien-Dindo score (p=0.039). A high PCI score correlated with increased ICU stay, 30 day mortality (p<0.001), and the need for postoperative ventilation (0.005).

CONCLUSIONS

PCI, duration of surgery and blood loss were major predictors of postoperative morbidity. Additionally, the amount of fluid given and delta temperature affected patient outcome and should be individualized to the patient's needs.

Complex Oncologic Surgeries and Implications for the Intensive Care Unit Nurse

There are many challenges in caring for the postsurgical patient in the intensive care unit. When the postsurgical patient has an active malignancy, this can make the intensive care unit care more challenging. Nutrition, infection, and the need for postoperative mechanical ventilatory support for the patient with cancer present challenges that may increase the patient's length of stay in the intensive care unit. Critical care nurses must be aware of these challenges as they provide care to this patient population.

Oncologic Emergencies

A new cancer diagnosis is expected to affect approximately 1.9 million people in the United States in 2021. A small percentage of these patients will experience an emergent cancer-related complication. Oncologic emergencies may be encountered in emergency departments or require intensive care management. Patients newly diagnosed with cancer are more likely to present with emergencies related to the underlying malignancies. Oncologic emergencies can have various manifestations, ranging from mechanical obstruction due to tumor growth to metabolic derangements due to abnormal secretions from the tumor. Therefore, early identification and treatment of life-threatening oncologic events is critical. Although there are several different types of oncologic emergencies, this article focuses on metabolic emergencies (tumor lysis syndrome and cytoreductive hyperthermic intraperitoneal chemotherapy) and structural emergencies (increased intracranial pressure and vena cava thrombus). The purpose of this article is to provide acute care clinicians with an overview of selected oncologic emergencies and their evidence-based management.

Perianesthesia Care of the Oncologic Patients Undergoing Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy: A Retrospective Study

PURPOSE

This study was to understand the perianesthesia care for patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS  + HIPEC).

METHOD

This is a retrospective study.

DESIGN

The perioperative electronic medical records of 189 CRS  + HIPEC surgical cases at a hospital of Western Pennsylvania from 2012 to 2018 were analyzed to study the characteristics of perianesthesia care for CRS  + HIPEC surgery.

FINDINGS

The patients' median age was 57 (range 21-83) years, and 60% were men. The mean anesthesia time was 10.47 ± 2.54 hours. Most tumors were appendix or colorectal in origin, and the mean peritoneal cancer index score was 16.19 ± 8.76. The mean estimated blood loss was 623 ± 582 mL. The mean total intravenous crystalloid administered was 8,377 ± 4,100 mL. Fifty-two patients received packed red blood cells during surgery. Postoperatively, 100% of the patients were transferred to the intensive care unit. A majority (52%) of patients were extubated in the operating room. Median lengths of hospital and intensive care unit stays were 13 and 2 days, respectively. A majority (73%) of patients had 1 or more postoperative complications and 29% of patients experienced major postoperative complications (Clavien-Dindo grade III or higher) during the hospital stay. Prolonged hospitalization was owing to gastrointestinal dysfunctions and respiratory failure related to atelectasis and pleural effusion.

CONCLUSIONS

CRS  + HIPEC is a major surgery with numerous challenges to the perianesthesia care team regarding hemodynamic adjustment, pain control, and postoperative complications, which demand training and future studies from the perianesthesia care team.

Peritoneal Cancers and Hyperthermic Intraperitoneal Chemotherapy

Cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy is an aggressive, potentially curative approach used to treat locoregional disease associated with primary and secondary malignancies of the peritoneum. It involves resection of all macroscopic disease larger than 2.5 mm, followed by instillation of hyperthermic chemotherapy directly into the peritoneum for higher drug exposure to microscopic disease. In select patients with primary peritoneal mesothelioma, pseudomyxoma peritonei, colorectal adenocarcinoma, appendiceal adenocarcinoma, or ovarian cancer, with no extra-abdominal metastasis and limited involvement of the peritoneum, the procedure can be performed to increase overall survival.

Hyperthermic intraperitoneal chemotherapy enhances blood coagulation perioperatively evaluated by thromboelastography: a pilot study

Background and Objectives: Postoperative thromboembolism is a significant cause of prolonged recovery in patients undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Thromboelastography (TEG) can detect hypercoagulable states and predict thromboembolic complications after surgery. This study assessed the impact of CRS and HIPEC on TEG values.Methods: TEG parameters reaction time (R), kinetics time (K), angle (α), maximum amplitude (MA), and lysis percent at 60 min (LY60) were determined preoperatively, and at the end of CRS, during HIPEC, and at the end of the operation using blood samples from 15 HIPEC patients. Platelets, P-TT, and aPTT were also determined before and after CRS.Results: A total of 75 samples were analyzed. During CRS, there was a significant reduction in the mean MA (3.06 mm, p = 0.001). The mean P-TT declined by 32% (p < 0.001) and mean platelets by 55 × 10⁹/L (p < 0.001). During HIPEC, the mean R and K shortened by 1.04 min (p = 0.015) and 0.18 min (p = 0.018), respectively, whereas α increased by 2.48° (p = 0.005).Conclusions: During CRS, both TEG and conventional laboratory tests indicated hypocoagulation. During HIPEC, however, the initiation of coagulation and the kinetics of thrombin formation were accelerated.

Society of Onco-Anaesthesia and Perioperative Care consensus guidelines for perioperative management of patients for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC)

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) for primary peritoneal malignancies or peritoneal spread of malignant neoplasm is being done at many centres worldwide. Perioperative management is challenging with varied haemodynamic and temperature instabilities, and the literature is scarce in many aspects of its perioperative management. There is a need to have coalition of the existing evidence and experts' consensus opinion for better perioperative management. The purpose of this consensus practice guideline is to provide consensus for best practice pattern based on the best available evidence by the expert committee of the Society of Onco-Anaesthesia and Perioperative Care comprising perioperative physicians for better perioperative management of patients of CRS-HIPEC.

Feasibility and benefits of an enhanced recovery after surgery protocol for patients undergoing cytoreductive surgery and heated intraperitoneal chemotharpy: A single institution experience

BACKGROUND

Cytoreductive Surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is reported to have a prolonged length of stay (LOS). We incorporated an enhanced recovery after surgery (ERAS) protocol to examine whether we could reduce our LOS.

METHODS

Patients were identified who underwent CRS/HIPEC from 2015 to 2018 before and after initiation of ERAS protocol. The protocol included pre-operative, peri-operative and post-operative interventions. Primary end point was LOS. Secondary endpoints were morbidity and mortality.

RESULTS

Forty patients were identified, thirty-one of which underwent CRS/HIPEC: 16 before and 15 after ERAS. The median LOS prior to ERAS was 11 days (5-20) and 7 days (5-27) after ERAS (P < 0.05). There was no significant difference in 30-day morbidity (Clavien-Dindo ≥3) or mortality between the groups.

CONCLUSIONS

An ERAS protocol can safely be implemented in patients undergoing CRS/HIPEC with earlier return of bowel function and decrease in LOS without increasing morbidity or mortality.

Anaesthetic management and perioperative outcomes of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy: A retrospective analysis

Background and Aims:

Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is becoming the standard treatment option for peritoneal carcinomatosis but is associated with high rates of morbidity and mortality. Our aim was to retrospectively analyse and evaluate intra-operative factors associated with morbidity and mortality of CRS and HIPEC.

Methods:

Intra-operative data were collected for cases done over 1 year (24 cases) and analysed for the primary outcome of post-operative ventilation >24 h, and secondary outcome of length of the Intensive Care Unit (ICU) stay >5 days. Statistical analysis was carried out in STATA 11 software.

Results:

Higher peritoneal carcinoma index (PCI), (P = 0.0047), longer duration of surgery (P = 0.0016), higher delta temperatures (P = 0.0119), increased estimated blood loss (EBL) (P = 0.0054), high intraoperative fluid requirement (P = 0.0038), lower mean arterial pressure (MAP) (P = 0.0021) and higher blood products requirement were associated with >24 h ventilation. These factors were also associated with longer ICU stay. All these factors associated with >24 h ventilation and prolonged ICU stay are related to the PCI which is an indicator of the extent of surgery.

Conclusion:

Higher PCI, longer duration of surgery, higher delta temperatures, increased EBL, high intraoperative fluid requirement, lower mean arterial pressure and higher blood products requirement were associated with >24 h postoperative ventilation as well as ICU stay >5 days. All these factors are related to the PCI, which is a major predictor of post-operative morbidity.
