The awareness of enhanced recovery after surgery (ERAS) cesarean delivery guidelines among anesthesiology and reanimation assistants in Turkey; a questionnaire study.

BACKGROUND: To reduce maternal-fetal morbidity and mortality, it is becoming increasingly important for anesthetists to understand and implement enhanced recovery after surgery (ERAS) cesarean delivery guidelines. Our aim was to reveal the knowledge of anesthesia assistants in Turkey about ERAS during cesarean delivery and to increase their awareness of ERAS. METHODS: This descriptive study was conducted in the city of Isparta, Turkey in 2023. The survey, which was approved by the ethics committee, was distributed to participants across Turkey via e-mail and online messages. The survey comprises of a total of 42 questions evaluating perioperative ERAS recommendations. RESULTS: Of the 404 participants in our survey, 59.9% were associated with university hospitals and 65.8% had completed three or more years of education. A total of 87.9% of the participants were familiar with ERAS; however, only 42.8% had received ERAS training. Although 93.8% of the participants' institutions performed a cesarean delivery, ERAS recommendations were only implemented at a rate of 48%. This may be due to the absence of an ERAS team, which was identified in our survey at a high rate of 66.6%. CONCLUSION: Awareness about ERAS was high among the participants, but the implementation rates of some recommendations were low. The reason for this may be the inability to form a multidisciplinary team and inadequate training of participants. For this purpose, we recommend the formation of a multidisciplinary team for ERAS protocol implementation and increased participant training opportunities.

Dexpanthenol ameliorates lipopolysaccharide-induced cardiovascular toxicity by regulating the IL-6/HIF1α/VEGF pathway.

Introduction: Lipopolysaccharide (Lps) is an essential component responsible for the virulence of gram-negative bacteria. Lps can cause damage to many organs, including the heart, kidneys, and lungs. Dexpanthenol (Dex) is an agent that exhibits anti-oxidative and anti-inflammatory effects and stimulates epithelialization. In this study, we aimed to investigate the effects of Dex on Lps-induced cardiovascular toxicity. Methods: Rats were divided into four groups: control, Lps (5 mg/kg, intraperitoneal), Dex (500 mg/kg, intraperitoneal), and Lps + Dex. The control group received saline intraperitoneally (i.p.) once daily for three days. The Lps group received saline i.p. once daily for three days and a single dose of Lps i.p. was administered on the third day. The Dex group received Dex i.p. once daily for three days and saline on the third day. The Lps + Dex group received Dex i.p. once daily for three days and a single dose of Lps i.p. on the third day. Heart and aortic tissues were taken for biochemical, histopathological, immunohistochemical, and genetic analysis. Results: Lps injection caused histopathological changes in both heart and aortic tissues and significantly increased total oxidant status and oxidative stress index levels. Interleukin-6, and Tumor necrosis factor-α mRNA expressions were significantly altered in heart and aorta, likely do to the anti-inflammatory and antioxidative effects of Dex. Furthermore, Dex affected Caspase-3 and Hypoxia-inducible factor 1-α staining patterns. Conclusions: Our results show that Dex treatment has a protective effect on Lps-induced cardiac and endothelial damage in rats by reducing inflammation, oxidative stress, and apoptosis.

Prevalence and Causes of Elective Surgery Cancellations After Patients are Taken to the Operating Room: A Prospective, Cross-Sectional Study.

Objective: This study aimed to investigate the causes and prevalence of elective surgery cancellations in the operating room, and the clinical outcomes of affected patients. Methods: This prospective, cross-sectional study assessed the prevalence and causes of elective surgery cancellations once patients are in the operating room. A tertiary academic referral center hosted the study between January 2022 and January 2023. The study sample consisted of 7,482 adult patients scheduled for elective surgeries and taken to the operating room. The 7,415 completed procedures were in Group 2, whereas the 67 cancelled surgeries were in Group 1. Patients were divided into two groups on the basis of whether their surgeries were completed or cancelled. Factors such as age, American Society of Anesthesiologists (ASA) status, and surgical department were analyzed. The two groups were compared on the basis of age, ASA status, surgical department, and surgery time (month and day). Results: Elective surgery cancellations occurred in the operating room at a rate of 0.9%. Group 1 was substantially older than Group 2 (p<0.001). Group 1 had a larger number of ASA III patients (p<0.001). The department with the highest cancellation rate was ophthalmology (2.5%), followed by general surgery (2.1%), urology (1.5%), and ear, nose, and throat (1.4%). It was possible to avoid 59.7% of cancelations. Conclusion: The study revealed a 0.9% prevalence rate of elective surgery cancelations in the operating room. Older age and higher ASA status greatly influenced these cancellations. Optimized surgery scheduling and patient assessment processes may prevent many of these cancellation.

[The effect of intra-articular levobupivacaine on shoulder cartilage at different doses-experimental study]. / O efeito de levobupivacaína intra­articular na cartilagem do ombro em doses diferentes­estudo experimental.

BACKGROUND AND OBJECTIVES: In this study it was aimed to examine the histological and morphometric effects on cartilage structure of intra-articular application of levobupivacaine to the shoulder joint. METHODS: In twenty New Zealand adult male rabbits, 35 shoulders were used for the study and prepared in 5 groups of 7. These groups were defined as Groups L1, L2, L3 and L4 which were right shoulders administered with 0.25% and 0.5% levobupivacaine, Group C which were left shoulders as the control group and Groups S1 and S2 which were left shoulders administered with 0.9% saline. On the 2nd and 15th days the animals were killed, the glenohumeral joints were evaluated macroscopically then cartilage samples were taken. These samples were evaluated with Mankin score, and histomorphometrically by measuring the thickness of the cartilage between the superficial cartilage layer and the tidemark and the thickness of calcified cartilage between the tidemark and the subchondral bone. RESULTS: Macroscopically, on the 15th day the joint fluid was seen to have reduced in all the groups. After microscopic evaluation, the highest Mankin score (mean: 3.14±2.1/14) was in the L4 group (15th day 0.5% levobupivacaine) and was found to be statistically significant (p<0.05). No statistically significant difference was determined between the other groups. CONCLUSIONS: Histologically, as the highest Mankin score was in the L4 group, this indicates that in a single intra-articular injection of levobupivacaine a low concentration should be selected. LEVEL OF EVIDENCE: Level 5, animal study.

Resumo Justificativa e objetivo: Neste estudo o objetivo foi examinar os efeitos histológicos e morfométricos sobre a estrutura da cartilagem da aplicação intra-articular de levobupivacaína em articulação do ombro. Métodos: Trinta e cinco ombros de 20 coelhos New Zealand, machos e adultos, foram usados para o estudo e divididos em cinco grupos de sete. Os grupos foram definidos como L1, L2, L3 e L4, consistiram em ombros direitos nos quais levobupivacaína a 0,25% e 0,5% foi administrada; o Grupo C, que consistiu em ombros esquerdos, foi o grupo controle; os grupos S1 e S2, que consistiram em ombros esquerdos, receberam solução salina a 0,9%. Os animais foram sacrificados no segundo e no 15º dia; as articulações glenoumerais foram avaliadas macroscopicamente e, em seguida, amostras de cartilagem foram coletadas. As amostras foram avaliadas com o escore de Mankin e histomorfometricamente. Mediu-se a espessura da cartilagem entre a camada superficial e a "linha de maré" (tidemark) e a espessura da cartilagem calcificada entre a tidemark e o osso subcondral. Resultados: Macroscopicamente, observou-se no 15º dia que o líquido articular havia reduzido em todos os grupos. Após a avaliação microscópica, o maior escore de Mankin (média: 3,14 ± 2,1/14) foi observado no grupo L4 (15º dia levobupivacaína a 0,5%), considerado estatisticamente significativo (p < 0,05). Nenhuma diferença estatisticamente significativa foi determinada entre os outros grupos. Conclusões: Histologicamente, como o maior escore de Mankin foi observado no Grupo L4, isso indica que em uma única injeção intra-articular de levobupivacaína uma concentração baixa deve ser selecionada. Nível de evidência: Nível 5, estudo em animais.
