Perioperative hemodynamic effects of dexmedetomidine as an adjuvant to 0.2% ropivacaine in ultrasonography guided interscalene brachial plexus block for elective shoulder arthroscopic surgeries under general anaesthesia: a prospective observational study
Background: Although an increasing number of anesthesiologists are using peripheral nerve catheters for postoperative analgesia, single shot blocks are still more common. Ropivacaine has become the most commonly used long-acting local anesthetic, and the duration of analgesia has been estimated to be 8 to 14 hours.Methods: The study was conducted from February 2020 to October 2021 after obtaining approval from the institutional ethics committee. The study was a prospective observational study.Results: Hemodynamic changes in patients who received dexmedetomidine in combination with Ropivacaine had a favorable reduction in both heart rate and blood pressure without causing any major side effect. Comparison of postoperative MAP (mmHg) in two groups at various intervals of time was observed and found to be statistically significant (p value of <0.05). Comparison of postoperative heart rate (beats/min) among two groups at various intervals of time was statistically significant (p value of <0.05).Conclusions: We can conclude that preoperative inter-scalene block given reduces the analgesic requirement intraoperatively as well postoperatively. And the hemodynamic changes in patients who received dexmedetomidine in combination with ropivacaine had a favorable reduction in both heart rate and blood pressure without causing any major side effect.
Post spinal anaesthesia shivering- incidence and associated risk factors in patients undergoing lower limb and abdominal surgeries
Background: This study was conducted to evaluate the incidence of shivering and likely associated risk factors following spinal anaesthesia in patients undergoing lower abdominal and lower limb surgeries.Methods: The present study was conducted in MMIMSR, Department of anaesthesia from December 2016 to September 2018. It was an observational study which was conducted over a period of 2 years. Patients who were scheduled to undergo elective lower abdominal and lower limb surgeries under spinal anaesthesia were included in study.Results: The present study depicts a high incidence of post spinal shivering, which was 42.8%. Majority of the patients belonged to the young age group between 20-30 years. The mean time of onset of shivering, was around 25 mins. Duration of shivering was observed between 15-75 minutess with a mean of 43.75 and SD±19.39.Conclusions: Shivering is one of the distressing complications of spinal block, which may be deleterious to the patients with poor cardio-respiratory reserve
Crocin: Functional characteristics, extraction, food applications and efficacy against brain related disorders
Crocin is a bioactive compound that naturally occurs in some medicinal plants, especially saffron and gardenia fruit. Different conventional and novel methods are used for its extraction. Due to some control conditions, recent methods such as ultrasonic extraction, supercritical fluid extraction, enzyme-associated extraction, microwave extraction, and pulsed electric field extraction are widely used because these methods give more yield and efficiency. Crocin is incorporated into different food products to make functional foods. However, it can also aid in the stability of food products. Due to its ability to protect against brain diseases, the demand for crocin has been rising in the pharmaceutical industry. It also contain antioxidant, anti-inflammatory, anticancer and antidepressant qualities. This review aims to describe crocin and its role in developing functional food, extraction, and bioavailability in various brain-related diseases. The results of the literature strongly support the importance of crocin against various diseases and its use in making different functional foods
