Is Vasoactive-Inotropic Score a Predictor for Mortality and Morbidity in Patients Undergoing Coronary Artery Bypass Surgery?

Abstract Introduction: We aimed to investigate whether vasoactive-inotropic score (VIS) is a predictor for early postoperative morbidity and mortality. Methods: This study was planned as a prospective cohort study, between Nov 20 2018 and May 15 2019, including a total of 290 patients aged 20 years or older who underwent elective on-pump coronary artery bypass grafting (CABG). Patients' demographic data, aortic cross-clamp and cardiopulmonary bypass times, European System for Cardiac Operative Risk Evaluation (EuroSCORE) score, cardiac ejection fraction (EF), VIS, intubation duration, and intensive care unit length of stay were recorded. Postoperative mortality and morbidity were recorded. Hourly doses of inotropes for VIS were recorded for each patient, and VIS was calculated. Results: Among the cases, 222 (77%) were male and 68 (23%) were female. The mean age of our patients was 62.5 years (37-86). Combined morbidity and mortality rates of our patients were 23.8%. An optimal cutoff point for VIS of 5.5 could predict combined morbidity and mortality with 90% sensitivity and 88% specificity. Low EF, prolonged operation time, high EuroSCORE, and high VIS are independent factors in the early postoperative period for the development of combined morbidity and mortality in patients who underwent elective CABG. Conclusion: VIS is the most critical and EuroSCORE is the second most important scoring systems. They independently predict combined morbidity and mortality in undergoing elective coronary artery bypass surgery.

[Transient Horner's syndrome after single shot paravertebral block]. / Síndrome de Horner transitória após bloqueio paravertebral em injeção única.

BACKGROUND: Thoracic paravertebral block can provide analgesia for unilateral chest surgery and is associated with a low complication rate. Horner syndrome also referred to as oculosympathetic paresis, is a classic neurologic constellation of ipsilateral blepharoptosis, pupillary miosis, and facial anhidrosis resulting from disruption of the sympathetic pathway supplying the head, eye, and neck. CASE REPORT: We present a patient with an ipsilateral transient Horner syndrome after ultrasound guided single shot of 15mL 0.25% levobupivacaine for thoracic paravertebral block at T5-6 level. CONCLUSIONS: It should be kept in mind that even a successful ultrasound guided single shot thoracic paravertebral block can be complicated with Horner syndrome due to unpredictable distribution of the local anesthetic.

[The relationship between preoperative anxiety levels and vasovagal incidents during the administration of spinal anesthesia]. / A relação entre os níveis de ansiedade no período pré­operatório e os incidentes vasovagais durante a administração de raquianestesia.

BACKGROUND: It was aimed to investigate the relationship between preoperative anxiety and vasovagal symptoms observed during the administration of spinal anesthesia in patients undergoing surgery in the perianal and inguinal regions. METHODS: The study included patients with planned surgery for inguinal hernia repair, anal fissure, hemorrhoid and pilonidal sinus excision. The study included a total of 210 patients of ASA I-II, aged 18-65 years. Patients were evaluated in respect of demographic characteristics, smoking and alcohol consumption, ASA grade and educational level. Correlations were evaluated between the number of attempts at spinal anesthesia and anesthesia history with vasovagal symptoms and educational level, gender, smoking and alcohol consumption and anesthesia history with anxiety scores. The instant (transient) state anxiety inventory part of the Transient State/Trait Anxiety Inventory (State Trait Anxiety Inventory - STAI) was used to determine the anxiety levels of the participants. Clinical findings of peripheral vasodilation, hypotension, bradycardia and asystole observed during the administration of spinal anesthesia were recorded. RESULTS: Vasovagal incidences during the administration of spinal anesthesia were seen to increase in cases of high anxiety score, male gender, and an absence of anesthesia history. Educational level and the number of spinal needle punctures were not found to have any effect on vasovagal incidents. CONCLUSION: The determination of causes triggering vasovagal incidents seen during the application of spinal anesthesia, better patient information of regional anesthesia implementations and anxiety relief with preoperative anxiolytic treatment will help to eliminate potential vasovagal incidents.
