The Total Intra Venous Anesthesia Effect Versus Volatile Anesthesia, on Stress and Pain Levels, in Patients Undergoing Breast Reconstruction in Ambulatory Surgery Center Total Intra Venous Anesthesia Protocol and Stress Response.

AIM: To compare pain and stress response through cortisol and DHEA levels, implementing. Total intra venous anesthesia (TIVA) versus general anesthesia with volatile anesthetics (VOL). DESIGN: This is a prospective randomized correlation study with consecutive measurements. METHODS: In an ambulatory surgical center from October of 2019 to August of 2020, patients who underwent breast reconstruction with autologous fat grafting were randomized into 2 groups. Patients in the TIVA group (n = 23) received intravenous anesthesia and those in the VOL group (n = 23) received volatile anesthesia (desflurane). Demographic, anthropometric and clinical data were recorded. Arterial systolic (SP) and diastolic (DP) blood pressure, heart rate and oxygen saturation were recorded. Pain and stress levels were evaluated through salivary cortisol and DHEA levels at 4 different time points: T0) 1 hour before induction, T1) during the induction, T2) during anesthesia maintenance, and T3) in recovery phase. Statistical analysis was performed with SPSS 25.0 at significant level α = .05. FINDINGS: There were no statistically significant differences between the 2 groups regarding demographic features. Interestingly that there was a statistically significant difference in the vital sign monitoring where patients in the TIVA group reported with higher levels of SP(T2) and DP (T2), whilst DHEA (T1) levels was correlated positively with patient's age and cortisol (T1) levels and negatively with DP (T3). CONCLUSIONS: This study supports the use of TIVA as a safe and effective option for anesthesia in patients undergoing breast reconstruction with autologous fat grafting.

Developing an enhanced recovery after surgery program for oncology patients who undergo hip or knee reconstruction surgery.

Enhanced recovery after surgery (ERAS) protocols are applied in orthopedic surgery and are intended to reduce perioperative stress by implementing combined evidence-based practices with the cooperation of various health professionals as an interdisciplinary team. ERAS pathways include pre-operative patient counselling, regional anesthesia and analgesia techniques, post-operative pain management, early mobilization and early feeding. Studies have shown improvement in the recovery of patients who followed an ERAS program after hip or knee arthroplasty, compared with those who followed a traditional care approach. ERAS protocols reduce post-operative stress, contribute to rapid recovery, shorten length of stay (LOS) without increasing the complications or readmissions, improve patient satisfaction and decrease the hospital costs. We suggest that the ERAS pathway could reduce the LOS in hospital for patients undergoing total hip replacement or total knee replacement. These programs require good organization and handling by the multidisciplinary team. ERAS programs increase patient's satisfaction due to their active participation which they experience as personalized treatment. The aim of the study was to develop an ERAS protocol for oncology patients who undergo bone reconstruction surgeries using massive endoprosthesis, with a view to improving the surgical outcomes.

Evaluating Preoperative Anxiety Levels in Patients Undergoing Breast Cancer Surgery.

OBJECTIVE: Patients' anxiety and stress levels are increased after the surgery. High levels of anxiety and stress could increase postoperative complications, as well as to prolong postoperative hospitalization and postoperative morbidity. This prospective, cross-sectional study was to evaluate the preoperative stress levels in patients undergoing breast cancer surgery. METHODS: In the study participated 165 female patients who underwent breast cancer surgery, in a major oncological hospital in Greece. Demographic and clinical data were collected, and anxiety and stress levels assessed using the State-Trait Anxiety Inventory (STAI) Scale, which was a self-report questionnaire consisting of 40, 4 Likert Scale questions. The first 20 questions, STAI-X-1, were concerned to how the patient felt while answering the questionnaire (anxiety as a condition) and the remaining 20 questions, STAI-X-2, based on how the patient felt overall (stress as a personality trait). Descriptive statistics and nonparametric tests were performed at a significance level alpha = 0.05. RESULTS: In the present study, 165 females were enrolled who underwent breast cancer surgery. The mean age of the participants was 55.86 years, whereas the mean body mass index was 26.85. The 60.6% of patients underwent a lumpectomy and 28.5% had mastectomy. The 35.8% experienced moderate levels of anxiety, and the 17.6% experienced high levels. The two scales were positively correlated (rho = 0.643, P < 0.001), at the significance level P = 0.01. Furthermore, the Stai-X-2 Scale was negatively correlated with body height (rho = -0.1188, P = 0.016). CONCLUSIONS: The present study showed that patients' personality influenced their anxiety levels. Thus, the role of the nurse is a cornerstone in their psychological support preoperatively, to reduce the anxiety and stress levels.
