INTRA-POST-OPERATIVE PHASE Flashcards
The Surgical Team is comprised of:
- Surgeon
- Anesthesiologist
- Scrub Nurse
- Circulating Nurse
TYPES OF ANESTHESIA
- General Anesthesia
- Regional Anesthesia
partial or total loss of sensation with or without loss of consciousness deliberately induced to prevent pain perception and promote relaxation during surgery
Anesthesia
Type of Anesthesia:
refers to the depression of the central nervous system by administration of drugs or inhalation agents; patients under this usually require ventilator assistance
General Anesthesia
Types of General Anesthesiaa
- Inhalation
- Intravenous anesthesia
- Rectal anesthesia
Type of General Anesthesia
administered through (1) open drop [anesthesia is roped directly into layers of gauze that is held on the patients’ mouth (2) mask
Inhalation
(halothane, ether, nitrous oxide, cyclopropane)
Type of General Anesthesia
commonly employed as induction agent prior to inhalation anesthesia
Intravenous anesthesia
(pentothal, ketalar)
How is General anesthesia accomplished in 4 phases:
- Pre-induction
- Induction
- Maintenance
- Reversal/extubation
Phase of General anesthesia:
Begins with the induction of anesthetic agents and ends with stabilization of the patient. Involves putting the patient safely to sleep.
Induction
Phase of General anesthesia:
Begins with closure of the wound and ends before patient transport to PACU
Reversal/extubation
suspension of sensation on affected site of the body; temporarily prevents generation and conduction of nerve impulses and may not affect motor functions
Regional Anesthesia
used for patients whom general anesthesia is contra indicated
Type of Regional Anesthesia:
injection into the surgical area making the receptor unresponsive to stimuli
Local
Type of Regional Anesthesia:
injection of an agent into the large trunk or nerve plexus
Peripheral Nerve Block (tetracaine)
Type of Regional Anesthesia:
injection of certain local anesthesia into subarachnoid space between l3 and l4 using a lumbar interspace, usually employed for almost any type of major operation below the level of diaphragm
Spinal anesthesia
Type of Regional Anesthesia:
introducing anesthetic agent into the epidural space (through the intervertebral space into the space surrounding the dura matter in the spinal column)
Epidural block
Type of Regional Anesthesia:
Insertion of long needles into acupuncture points
Acupuncture
Type of Regional Anesthesia:
Use of cold to induce anesthesia
Cryothermaia
Guedel’s Classification of the Stages of Anesthesia
- Stage I (stage of analgesia)
- Stage II (stage of delirium/ excitement)
- Stage III (stage of surgical anesthesia)
- Stage IV (stage of danger/ medullar stage)
Guedel’s Classification of the Stages of Anesthesia:
begins with the administration of anesthetic agent and ends with the loss of consciousness; patients become drowsy, dizzy; the last sense to be depressed is hearing and first to return.
Stage I (stage of analgesia)
Guedel’s Classification of the Stages of Anesthesia:
begins with the loss of consciousness and ends with the onset of regular breathing and loss of eyelid reflexes; often companied by involuntary muscle activity
Stage II (stage of delirium/ excitement)
the patient should no receive auditory or physical stimulation during this period
Guedel’s Classification of the Stages of Anesthesia:
begins with the onset of regular breathing and ends with the cessation of respirations.
Stage III (stage of surgical anesthesia)
Guedel’s Classification of the Stages of Anesthesia:
begins with the cessation of respiration and leads to death.
Stage IV (stage of danger/ medullar stage)
Factors to consider in determining the type of anesthesia:
- Age and physical condition of the patient
- Type, location and duration of surgery
- Degree of technical intricacy of surgery
- Previous anesthetic history
- Personal preference, expertise and judgment of anesthesiologist
- Patient’s preference
Commonly Used Operative Positions
