 Preoperative radiologic examinations are diagnostic imaging tests used to evaluate a patient's anatomy and function before surgery. These exams help identify any underlying conditions that may affect the surgical procedure, assist in surgical planning, and help predict potential complications. The type of radiologic test ordered depends on the patient's medical history, the type of surgery being planned, and institutional protocols. Here’s an overview of common preoperative radiologic examinations: 1. Chest X-ray (CXR) Purpose : To assess the lungs, heart, and bones of the chest. Indications: For patients over 50 years of age or those with respiratory, cardiac, or other chronic diseases. Preoperative screening in patients undergoing major surgery or those with a history of smoking. Findings: Can reveal pneumonia, congestive heart failure, lung masses, or abnormal heart size. Important for detecting undiagnosed pulmonary conditions that may require attention during anesthesia o

  Essential Preoperative Tests You Need to Know About Preoperative tests are a set of essential medical screenings performed before a planned (elective) surgery. Even if you're in good health, these tests provide crucial insights into any underlying conditions that could affect your surgery or recovery. The specific tests you'll need before your operation depend on various factors, such as your age, overall health, medical history, medications, and the type of surgery you’re having. Let’s take a closer look at the most common preoperative tests and their purposes: 1. Full Blood Count (FBC) A Full Blood Count measures the levels of red blood cells, white blood cells, and platelets in your blood. This test helps detect conditions like anemia or thrombocytopenia (low platelet count), which could increase your risk of bleeding during surgery. If any abnormalities are found, your medical team may take extra precautions to minimize risks. 2. Blood Clotting Tests These tests, includin

Processing of Laparoscopic Instruments                Glutaraldehyde formulations are the most popular chemical germicides for high-level disinfection of laparoscopic and endoscopic equipment.   Optimal processing of LI involves several steps that reduce the risk of transmitting infection. These are : 1) Dismantling  Dismantle all removable parts for thorough cleaning.  2)Decontamination  The procedure begins in the theatre itself using the nursing staff wiping off visible blood tissue and body fluids in the instruments with a damp sterile sponge. At the conclusion of this all soiled or contaminated instruments should be placed in a container containing a disinfectant solution such as 0.5% chlorine and allowing them to soak for Ten minutes. 3) Precleaning  Following the instruments reach the sterile supplies processing area, which is preferably a controlled environment, a pre-cleaning treatment with an enzymatic method ( protease, amylase, lipase etc.) is recommended   4) Cleaning  Ul

Robotic assisted surgery   allow a surgeon at a console to operate remote-controlled robotic arms, which may facilitate the performance of procedures. These robotic systems are designed to enhance the surgeon's precision, control, and dexterity, offering potential benefits to both the surgeon and the patient. 1. Robotic System: The surgeon operates from a console equipped with a 3D visualization system and manipulates the robotic arms using hand and foot controls. 2. Enhanced Precision : Robotic systems provide enhanced precision by filtering any hand tremors of the surgeon's movements. The robotic arms translate the surgeon's hand movements into smaller, more precise movements, reducing the risk of human error. 3. Minimally Invasive: Robot-assisted surgery is typically performed using minimally invasive techniques, such as laparoscopy or thoracoscopy. Minimally invasive procedures involve smaller incisions compared to traditional open surgery, resulting in reduced scarring

Dosimeters A batch dosimeter is a type of radiation dosimeter that is designed to measure the amount of radiation exposure over a specific period , typically over several weeks or months.   Batch dosimeters are often used in occupational settings where workers may be exposed to radiation regularly, such as in nuclear power plants, medical facilities, or research laboratories. They are also relatively inexpensive and easy to use, making them a practical option for many occupational settings. Radiation workers who are issued single badges for monitoring whole-body dose should wear them in the region of the collar with the label facing out. When a lead apron is worn, the dosimeter should be outside the lead apron.  Technologists who work with fluoroscopy may wear two badges , one on the collar outside the lead apron and one at the waist that is under the apron. The two dosimeters should be distinguished by color or icons indicating their specific locations. Personnel who are issued dosime
