Medical and chemical evaluation of robotic surgery methods; A review study

Along with the advances in medical science, surgical methods have also undergone many advances. Today, with the advancement of technology in all fields, including medicine, robots have entered medical science. These robots have many uses as well as advantages and disadvantages that they enjoy in Iran and other countries. In this study, it was addressed. This study is a review of robotic surgery methods in Iran and other countries in the form of a review study. This study is a conceptual review. The steps performed are 1- Designing a research question, 2- Searching and extracting research- related studies, 3- Selecting related studies, 4- Tabulating and summarizing information and data, and 5- Reporting results. The results showed that robotic surgery in operations such as brain, kidney, open heart, liver, eye, laparoscopy, dental surgery, coronary artery surgery, hysterectomy, lymphadenectomy, general surgery, obstetrics, head and neck, shelf Chest, urology, endoscopy, colonoscopy, ear, nose, and throat are used and have advantages such as three-dimensional vision, flexible rotation of the instrument, reduction of surgeon hand vibration with vibration filter, ease of surgery and the ability to create the required patterns It reduces the volume of blood lost during surgery, the length of stay in the hospital, the amount of pain, and subsequently the number of analgesic doses consumed in the postoperative ward. Disadvantages include the relative increase in operating time, the high cost of robots, and the physician's lack of sensory perception of the patient's environment.

Medical and chemical efficacy of respiratory physiotherapy and Remdesivir in patients with COVID-19 pneumonia: A systematic review and meta-analysis

Evaluated efficacy of Respiratory Physiotherapy and Remdesivir on patients with COVID-19 pneumonia. In current systematic review and meta-analysis study, articles published January 2019 to December 1, 2021 were reviewed in the databases of PubMed, Scopus, Web of Science, and EBSCO. Risk ratio and mean differences with 95% confidence interval (CI), fixed effect model and Mantel–Haenszel or Inverse-variance formula were calculated. The Meta analysis have been evaluated with the statistical software Stata/MP v.16 (The fastest version of Stata). Mean differences of PaO2/FiO2 ratio at 6h after chest Respiratory Physiotherapy was (MD, 66 mmHg 95 % CI 64.71 mmHg, 67.28 mmHg; p=0.0007). Risk ratio of recovery rate between experimental and control group was 0.20 (RR, 0.20 95 % CI 0.15, 0.25) with high heterogeneity (I2 =78.84%; p=0.00). Risk ratio of mortality rate between experimental and control group was -0.34 (RR, -0.34 95 % CI -0.65, - 0.03) with low heterogeneity (I2<0%; p=0.51). Based on the findings of meta-analysis, Respiratory Physiotherapy can play an effective role in respiratory therapy and rehabilitation of patients admitted to the ICU with COVID-19. A meta-analysis showed that treatment with Remdesivir could increase the recovery rate, especially in the early days of COVID-19; also reduces the mortality rate.
