Feasibility and effectiveness of opioid-free anesthesia in cytoreductive surgery with or without heated intraperitoneal chemotherapy.

BACKGROUND: Opioid-free anesthesia (OFA) provides analgesia minimizing opioids. OFA has not been evaluated in cytoreductive surgery (CRS) with or without heated intraperitoneal chemotherapy. We aim to evaluate OFA feasibility and effectiveness in CRS. METHODS: Retrospective cohort study of adult patients (84) undergoing CRS in a tertiary center from May 2020 until June 2021. Predefined protocols for either opioid-based anesthesia (OBA) or OFA were followed. RESULTS: OFA protocol patients (41) had better mean pain scores (1 ± 0.8 vs. 2 ± 1; p = 0.00) despite the avoidance of intravenous and epidural fentanyl intraoperatively (220 ± 104 and 194 ± 73 µg, respectively, in OBA vs. 0; p = 0.00). Postoperative epidural levobupivacaine was also lower in the OFA group (575 ± 192 vs. 706 ± 346 mg; p = 0.034) despite the lack of epidural fentanyl without difference in duration (4.3 ± 1.2 vs. 4 ± 1.2 days; p = 0.22). Morphine consumption was very low (4.1 ± 10 vs. 1.7 ± 5 mg; p = 0.16). Intraoperative hypertensive events and postoperative nausea and vomiting (PONV) were higher for OBA (43) (30.2% vs. 7.3%; p = 0.01% and 69.8% vs. 34.1%; p = 0.001, respectively). Postoperative epidural fentanyl was independently associated with PONV (p = 0.004). There was no difference in total complications or length of stay. CONCLUSION: OFA is feasible, safe, and offers optimal pain control while minimizing the use of opioids in CRS.

Resultados de morbimortalidad en cáncer colorrectal en paciente quirúrgico frágil. Implementación de un Área de Atención al Paciente Quirúrgico Complejo / Colorectal carcinoma in the frail surgical patient. Implementation of a Work Area focused on the Complex Surgical Patient improves postoperative outcome

INTRODUCCIÓN: La edad avanzada y la presencia de comorbilidades repercuten en la morbimortalidad postoperatoria del paciente quirúrgico frágil. El objetivo de este estudio es valorar los resultados de morbimortalidad tras cirugía por cáncer colorrectal en el paciente quirúrgico frágil tras la implementación de un Área de Atención al paciente Quirúrgico Complejo (AAPQC). MÉTODOS: Estudio retrospectivo con recogida prospectiva de datos. Un total de 91 pacientes consecutivos considerados como frágiles (ASAIV o ASAIII con Barthel < 80 i/o Pfeiffer>3) fueron intervenidos entre 2013 y 2015 con diagnóstico de cáncer colorrectal con intención curativa. Grupo I (AAPQC): 35 pacientes incluidos en AAPQC durante 2015. Grupo II (No AAPQC): 56 pacientes intervenidos entre 2013 y 2014 previa implementación del AAPQC. Se analizó homogeneidad de grupos, complicaciones, estancia media, mortalidad, reintervenciones, reingresos y costes en función del GRD. RESULTADOS: No se encontraron diferencias significativas en edad, sexo, ASA, índex de masa corporal, estadio tumoral y tipo de intervención quirúrgica entre los dos grupos. Las complicaciones mayores (Clavien-DindoIII-IV) (11,4% vs. 28,5%, p = 0,041), la estancia media (12,6 ± 6 días vs. 15,2 ± 6 días, p = 0,043), los reingresos (11,4% vs. 28,3%, p = 0,041) y el peso específico del episodio (3,29 ± 1 vs 4,3 ± 1, p = 0,008) fueron significativamente menores en el grupo AAPQC. No hubo diferencias en re intervenciones (6,2% vs. 5,3%) ni mortalidad (6,2% vs 7,1%). El 96,9% de pacientes del grupo I manifestó una atención y calidad de vida satisfactoria. CONCLUSIONES: La implementación de una AAPQC en pacientes frágiles que deben ser intervenidos de cáncer colorrectal comporta una reducción de las complicaciones, estancia y reingresos, y es una medida coste-efectiva

INTRODUCTION: Advanced age and comorbidity impact on post-operative morbi-mortality in the frail surgical patient. The aim of this study is to assess the impact of a comprehensive, multidisciplinary and individualized care delivered to the frail patient by implementation of a Work Area focused on the Complex Surgical Patient (CSPA). METHODS: Retrospective study with prospective data collection. Ninety one consecutive patients, classified as frail (ASAIII or IV, Barthel<80 and/or Pfeiffer>3) underwent curative radical surgery for colorectal carcinoma between 2013 and 2015. GroupI: 35 patients optimized by the CSPA during 2015. Group II: 56 No-CSPA patients, treated prior to CSPA implementation, during 2014-2015. Group homogeneity, complication rate, length of stay, reoperations, readmissions, costs and overall mortality were analyzed and adjusted by Diagnosis-Related Group (DRG). RESULTS: There were no statistically significant differences in term of age, gender, ASA classification, body mass index, tumor staging and type of surgical intervention between the two groups. Major complications (Clavien-DindoIII-IV) (12.5% vs. 28.5%, P = .04), hospital stay (12.6 ± 6 days vs. 15.2 ± 6 days, P = 0.041), readmissions (12.5% vs. 28.3%, P < 0.041), and patient episode cost weighted according to DRG (3.29 ± 1 vs. 4.3 ± 1, P = 0.008) were statistically inferior in Group CSPA. There were no differrences in reoperations (6.2% vs. 5.3%) or mortality (6.2% vs. 7.1%). 96.9% of patients of Group I manifested having received a satisfactory attention and quality of life. CONCLUSIONS: Implementation of a CSPA, delivering surgical care to frail colorectal cancer patients, involves a reduction of complications, length of stay and readmissions, and is a cost-effective arrangement
