Many surgical procedures can be completed safely and painlessly by employing local anesthesia or sedation alone, which often proves cheaper, quicker, and safer than general anesthesia.
Prior to the 1850s, surgeons would practice on cadavers without anesthesia – which was risky because even one mistake could result in gangrene, blood poisoning or death.
Prior to anesthesia, surgeons could only perform certain surgeries because their patients would experience such intense discomfort that they could no longer move or speak; until antiseptic techniques were first developed in 1860s.
Under general anesthesia, you’re given medications to induce deep sleep so that no discomfort will be felt during surgery. These may be administered by either a physician or nurse anesthetist.
In certain instances, doctors and nurses can administer general anesthesia through a tube that goes directly into your mouth and windpipe (trachea).
With modern equipment, medications, and safety standards in place, most people do not experience serious adverse reactions from general anesthesia. It may cause some side effects like dry mouth or sore throat and nausea which usually pass after the anesthesia wears off; occasionally general anesthesia can result in dangerous drops in blood pressure or heart rate that require treatment via medication or breathing machines.
Regional anesthesia involves injecting anesthetic medication near nerves responsible for providing sensation to specific parts of your body, such as your arm or leg. This procedure may either replace general anesthesia entirely or act as a supplement.
UCLA physicians carefully consider your medical history, type of surgery and any other pertinent factors before suggesting a nerve block for you. Together with you surgeon and anesthesiologist they make this decision together.
Some types of nerve blocks can provide long-term pain relief by decreasing the need for opioid painkillers following surgery and also helping reduce blood loss – one of the main complications associated with surgery.
Your anesthesiologist can administer regional anesthetic using ultrasound technology and imaging equipment, to ensure the injection site is targeted appropriately and reduce any risk of complications like numbness around its injection point. Serious adverse reactions due to regional anesthetic are uncommon.
Local anesthesia provides relief during medical procedures by stopping nerves at the site of surgery from sending signals to centers in your brain that perceive pain. This form of anesthesia is typically used during minor medical procedures like skin biopsies and cataract surgery, among others.
Local anesthetic drugs are extremely safe, and serious complications are uncommon. You may experience temporary side effects after treatment such as sore throat or nausea – however if they persist tell your physician immediately as this could indicate serious medical conditions that require further investigation.
Your anesthesia treatment for this procedure will include similar drugs to IV sedation (twilight sleep), such as numbing medication and anxiety reducers. As with IV sedation (twilight sleep), however, care must be taken until the effects wear off before moving, since you may not notice if an injury occurs until then. Furthermore, each injection will contain small doses of lidocaine with epinephrine to minimize bleeding.
Under certain circumstances, such as surgery to treat brain tumors or epileptic seizures, surgeons need to operate while you are awake – this process is known as awake craniotomy and allows surgeons to map which parts of your brain control different functions so they don’t accidentally resect or remove function-bearing brain tissue.
Additionally, this approach allows surgeons to evaluate both the operation and results in real time, which allows many orthopaedic and gynaecological surgeries that would previously have required general anesthesia to now be completed using local anesthesia alone.
No matter the type of anesthesia you receive, it is crucial that you inform your physician of any use of cigarettes, alcohol or illegal drugs in the past or current time period. Such substances can negatively impact the heart, lungs and liver and alter how anesthesia works for you. Furthermore, discussing both your personal health history as well as family ties prior to surgery with the physician is also advisable.
