FAQs:
How much training does an anesthesiologist have?
Anesthesiologists are MDs who have completed at least three years of specialized residency training in Anesthesiology (after graduating from medical school and completing a year of internship in medicine or surgery). Many anesthesiologists, like myself, also have additional training in internal medicine, pediatrics, or surgery. Anesthesiologists are physicians who have a detailed understanding of human physiology and disease processes in addition to their specialized technical skills and knowledge. They possess diagnostic skills which they use to assess patients undergoing anesthesia in order to prevent problems during and after surgery.
What is the “Anesthesia Care Team” at Kaiser Permanente Medical Center in Santa Rosa?
Most anesthetic care at our medical center is delivered by an integrated team consisting of an anesthesiologist and a nurse anesthetist working under the direction of the anesthesiologist. Nurse anesthetists are highly trained nurses who specialize exclusively in the administration of anesthesia. Our anesthesiologists and nurse anesthetists work closely and collaboratively to meet each patient’s needs in multiple ways. We believe that our team approach provides the highest quality of care.
What are the different types of anesthesia?
There are 3 major categories of anesthesia: local, regional, and general. Each has its own advantages depending on your medical condition and the surgical procedure. Within each category, there are many different techniques and approaches. Sometimes techniques from different categories of anesthesia are combined to get “the best of both worlds.” You can read about the different types of anesthesia in detail under Types of Anesthesia in the Health Encyclopedia.
If I have a general anesthetic, what drugs will be used?
Anesthesia is complex and usually involves multiple medications. Some anesthetic medications are injected intravenously and some are inhaled. The type and amount of medication depend on the individual patient’s needs including the patient’s condition, the surgical procedure being performed, and very importantly the patient’s physiologic responses to both anesthesia and surgery. The use of multiple agents in a balanced approach allows us to get the best effects of each drug without giving large doses of any one drug that could cause unwanted side effects. Every patient is unique and therefore every anesthetic is slightly different, tailored exactly to each individual patient’s needs based on careful measurements of physiologic variables during surgery.
If I have a local anesthetic, will I be awake?
Perhaps. We usually sedate patients to keep them relaxed and comfortable during local anesthesia. Depending on your preferences and the nature of the surgery, more or less sedation may be given. For cataract surgery, for example, we usually use minimal sedation – just enough to relax you a bit. For hernia surgery, more sedation is often necessary to assure that patients are very comfortable. So patients may or may not be awake, or often are intermittently awake, during surgery under local anesthesia. In addition, due to the effect of sedative drugs on memory, many patients who are awake and conversant during surgery under local anesthesia have no memory of the time during, or immediately before or after, their surgery. In all cases we will make sure that you are relaxed and comfortable.
If I have a regional anesthetic, will I be awake?
This is essentially the same answer as above. Note that one exception is during caesarian sections under epidural or spinal anesthesia, when minimal or no sedation is used (to protect the baby from sedative effects) and the mother is quite awake. The anesthesiologist or nurse anesthetist will be there throughout the procedure to care for you and reassure you, and we can safely administer small amounts of sedation if needed. One beneficial aspect of minimal or no sedation during caesarian section is that the mother will usually have a clear memory of the birth of her baby.
How do you decide how much anesthetic to give me?
We base initial doses on your size, age, medical condition, and the procedure that will be performed. Subsequent doses are based primarily on our monitoring of your body’s vital functions including the heart, the circulation, your breathing, and your degree of muscle relaxation.
Will I have a breathing tube?
Sometimes but not always. Most procedures under general anesthesia require a breathing tube of some sort. The two most common devices used are an endotracheal tube (ETT) which goes into the windpipe (trachea), or a laryngeal mask airway (LMA) which sits in the back of the throat just above the windpipe. Which device you have will be based on your procedure, your medical condition, and a number of other factors. You should feel free to discuss this with your anesthesiologist if you wish. Major procedures in the abdomen and thorax almost always require an ETT. Rest assured that you will be deeply asleep before a breathing device of any type is placed. (The only exception to this is in some unusual situations when we feel it is safest to numb your mouth and throat very well with local anesthetic spray and then place the tube gently using a flexible fiberoptic scope, while you are sedated.)
How long will it take for me to recover from anesthesia?
This is highly variable and depends primarily on your condition before surgery and the type of surgery you are having. For short outpatient procedures, recovery from general anesthesia is often quite rapid (1-2 hours). For longer, major procedures, you may remain sleepy from your anesthesia for several hours or even overnight. Epidural anesthesia usually takes about 2 hours or so to wear off. Spinal anesthesia varies more and may in some cases take up to a few hours to wear off. Local anesthesia, even with significant sedation, usually affords the speediest recovery (often under an hour). For most patients, the biggest determinant of how long you will need to be in the recovery area will not be your anesthetic recovery time but rather your need for pain control or nausea control after surgery.
Why do I have to fast before anesthesia and surgery?
We take numerous precautions to prevent any problems due to vomiting while under anesthesia. As a result, complications from vomiting during anesthesia are extremely rare. Among the many precautions we take to decrease the risk of vomiting is to have you fast for up to 8 hours before surgery. Fasting decreases the volume and the acidity of your stomach contents.
Will I vomit after surgery?
Sometimes patients are nauseated and may vomit after surgery. This is most common with abdominal procedures, gynecologic surgery, and eye surgery. It is more common in women than men, and more common in people who are prone to motion sickness. We take numerous measures to prevent nausea and vomiting after surgery, including using anesthetics that have an anti-nausea effect and administering anti-nausea medications before, during, and after surgery.
Does spinal anesthesia cause permanent paralysis sometimes?
Spinal anesthesia has long been known to be extremely safe when practiced by skilled practitioners. Permanent paralysis or any damage to the spinal cord or spinal nerves after spinal anesthesia is extremely rare.
What is the difference between an epidural and a spinal anesthetic?
Spinal anesthesia involves injection of a very small dose of local anesthetic directly into the spinal fluid, using a very small needle. It is usually a “one-shot” approach without a catheter (tiny plastic wire-like tube) for repeat dosing. The lower part of your body will usually get very numb immediately. Epidural anesthesia involves placing a small catheter through a needle into a space called the epidural space, which can be thought of as a sheath around the spinal cord and spinal nerves. The needle is removed but the catheter stays in place in order to allow continuous or repeated dosing as needed. The onset of epidural anesthesia is slower than spinal, about 10-20 minutes. Epidural is most commonly used when repeated dosing is likely to be necessary (such as during labor, or for longer surgery) because the catheter makes repeat injections easy. The risks of spinal and epidural anesthesia are similar, and the procedures usually feel quite similar to the patient (numbing the skin of the lower back, placing the needle, injecting medication). In almost all cases, the skin and tissues beneath the skin are well-numbed using a tiny needle and local anesthetic, so that both spinal and epidural procedures are painless or cause only very slight discomfort.
Will lying flat for 24 hours help prevent a spinal headache from developing?
No. That is an old wive’s tale. However, if you do develop a spinal headache, you will feel better if you lie down. Then call the hospital operator and have her page the anesthesiologist on call - he/she will offer you some options to relieve your headache.
Will I “wake up” during general anesthesia?
Awareness under general anesthesia is extremely rare. Fortunately, it is so rare that I personally have never had a known case of awareness under general anesthesia in any of my patients in over 20 years of busy practice. We use many techniques to prevent this rare and very serious event from occurring – no one technique or monitor is sufficient. Clinical reports and research in this area have shown that patients who believe they were or might have been awake during general anesthesia benefit greatly from discussing this with their surgeon and anesthesiologist as soon as possible, and getting therapy promptly to prevent it from causing further distress.
