How to prevent retractor fatigue during surgery?

Image
  Retractor Fatigue During Surgery A retractor is a surgical instrument used to hold back or separate tissues during a surgical procedure. It is typically a flat or curved blade with a handle that can be adjusted to various angles. Retractors are commonly used in various types of surgeries, such as abdominal, thoracic, and orthopedic procedures, to provide better visibility and access to the surgical site. They can also be used to hold organs or other structures in place during a procedure. Retractor fatigue during surgery refers to the physical exhaustion that can occur in surgeons when using retractors for prolonged periods of time during an operation. This can lead to decreased precision and increased risk of errors.  Manual retraction, a task performed to expose the surgical site, poses a high risk for musculoskeletal disorders that affect the hands, arms, shoulders, neck, and back(1).   To prevent retractor fatigue, surgeons may take frequent breaks, use ass...

Mono vs Bipolar Cautery

 Mono vs Bipolar Cautery  Cautery may be a therapeutic method utilized to evacuate or crush undesirable tissue or control bleeding by applying heat to the affected area.  The initial incision is made by a scalpel. The Electrosurgical unit (ESU) is not used to incise the skin. Electrosurgery can be used on fat, fascia, muscle, internal organs, and vessels. ESUs operate at frequencies between 100,000 and 1 0,000,000 Hz. This current can be passed through tissue without causing stimulation of muscles or nerves. Electrosurgery differs from electrocautery. Electrocautery is the use of a unidirectional current generated by a self-contained battery-operated disposable instrument with a wire at the tip. The wire heats when activated and coagulates the tissue. The energy does not enter the patient’s body. The ESU uses an alternating current that passes through the patient’s tissues and returns to the generator.  Two forms of cautery are commonly used in surgery:  ...

Difference between anesthesia machine & ventilation machine

Image
  An   anaesthetic machine   ( British English ) or   anesthesia machine   ( American English ) is a   medical device   receives medical gases (oxygen, nitrous oxide, air) under pressure and  accurately controls the flow of each  gas individually. A gas mixture of  the desired composition at a define  flow rate is created before a known  concentration of an inhalational  agent vapour is added. Gas and  vapor mixtures are continuously  delivered to the common gas outlet  of the machine, as fresh gas flow  (FGF) , and to the breathing system  and patient . Components of anesthesia machine: It consists of  1.Gas supplier 2. Pressure gauges 3. Pressure regulators (reducing  valves) 4. Flowmeters 5. Vaporizers 6. Common gas outlet 7. A variety of other features, e.g.  high-flow oxygen flush, pressure  relief valve and oxygen supply  f ailure alarm and suction  apparatus 8....
