INTRAOP PT.2 (my copy)

Topical Application

• Anesthetic agent applied directly into the mucosal membrane to a serous surface or into an open wound.

• may be applied such as the skin, inside the mouth or throat, in the nose, or in the eyes.

Local Infiltration Anesthesia/ Local Anesthesia (LA)

Injected into the tissue around the incisional area

Field Block

Anesthetic agent is introduced around the operative field through a series of injections

Peripheral Nerve Block (PNB)

Administered directly into or around one nerve or group of nerves into the involved area that control sensation and movement to a specific part of the body.

Intravenous Block (Bier block)

• often used for arm, wrist and hand procedure

• is a type of regional anesthesia where a local anesthetic is injected into a vein, causing temporary numbness and loss of sensation in the distal part of the limb.

• an occlusion tourniquet is applied to the extremity to prevent infiltration and absorption of the injected IV agents beyond the involved extremity

Caudal Anesthesia/Caudal Block

Is produced by injection of the local anesthetic into the caudal or sacral canal or anesthesia in the perineum

Spinal Anesthesia/Sub-arachnoid Block (SAB)

Anesthetic agent is introduced into the cerebrospinal fluid (CSF) in the subarachnoid space

Epidural Anesthesia

• Administered into the epidural space.

• It involves injecting a local anesthetic into the epidural space around the spinal cord, providing pain relief for surgeries or labor.

• Sometimes a small tube or catheter is inserted into the epidural space, which allows the anesthesiologist to administer more medications as needed.

• often used when long term pain relief is needed

• Continuous Lumbar Epidural Anesthesia (CLEA)

• Combined Spinal Epidural Anesthesia (CSEA)

• Continuous Thoracic Epidural Anesthesia (CTEA)

Types of Epidural Anesthesia

Continuous Lumbar Epidural Anesthesia (CLEA)

• continuous injection of an anesthesia solution into the sacral and lumbar plexuses within the epidural space to relieve the pain of childbirth

• also used in general surgery to block the pain pathways below the navel.

Combined Spinal Epidural Anesthesia (CSEA)

• a regional anesthetic technique, which combines the benefits of both spinal anesthesia and epidural anesthesia.

• The indwelling epidural catheter gives the ability to provide long lasting analgesia and to epidural and to titrate the does given to the desired effect.

Continuous Thoracic Epidural Anesthesia (CTEA)

• Thoracic epidural analgesia remains a critical tool for anesthesiologist to use in acute pain.

• Is particularly effective for reducing pain after thoracic and abdominal surgery, and rib fractures

Injection Sites

ANAPHYLACTIC SHOCK

Danger caused by idiosyncrasy of the anesthetic.

HEMORRHAGE

It may cause shock, cardiac arrhythmia, or even death

EMBOLI

air embolism may result from accidental introduction of air into the circulatory system.

CONVULSIONS

danger caused by carbon dioxide retention, air embolism, over dosage of regional drugs.

CARDIAC ARREST

A sudden cessation of cardiac function.

CIRCULATORY DEPRESSION OR SHOCK

danger caused by hemorrhage, fast moving of the unconscious patient, rough handling of tissues, or severe fright.

CORONARY THROMBOSIS

danger from severe hypoxia.

CARDIOVASCULAR OCCLUSION

danger from sudden drop of blood pressure

CEREBRAL HEMORRHAGE

caused by sudden increased in blood pressure.

CEREBRAL EDEMA

from cerebral hypoxia. As prevention, move anesthetized patient gently & slowly to allow the circulation to adjust to position to change

BRONCHOSPASM & LARYNGOSPASMS

are caused by certain allergic conditions.

ASPIRATION

may occur during abolition of throat reflexes when the patient is unconscious.

Draping

Purpose is to create and maintain an adequate sterile field during operation.

Counting

Method of accounting for items placed on the sterile table for use during the surgical procedure

Baseline count

• during set-up for the surgical procedure

• As scrub nurse touches each item, he/she and the circulator count each item ALOUD until finished.

• Circulator then documents count for each type of item

• Counting should not be interrupted

• If the scrub/circulator is PERMANENTLY relieved by another person during surgery, the incoming person should verify all counts.

1st closing count

• done before the surgeon starts the closure of a body cavity or a deep large incision

• Field count – surgical field

• Table count – Mayo stand and instrument table

• Floor count – materials recovered from the floor

2nd closing count

• done during skin closure

• Circulator totals the field, table and floor counts

• If final count = total in the tally sheet, circulator informs the surgeon that counts are correct

Incorrect count

• The surgeon is informed immediately

• The entire count is repeated

• Circulator – searches the trash receptacle, under the furniture, floor, laundry hamper and throughout the room

• Scrub – searches the drapes and items in the OR table and Mayo stand

• Surgeon – surgical field and wound

• Circulator – inform OR supervisor to check count and assist with search

• Circulator – completes an Incident Report (IR)

X-ray

If all measures exhausted in incorrect count:

• Butterfly incision – for craniotomy

• Limbal incision – for eye surgeries

• Halstead / Elliptical incision – for breast surgeries

• Abdominal incision – for abdominal surgeries  

• McBurneys incision – for appendectomy

• Pfannenstiel – for CS

• Lumbotomy or transverse incision – for kidney surgeries

Common Surgical Incision (BLHAMPL)

• Type of surgery (anatomical location)

• Maximum exposure

• Ease and speed of entering (for emergency surgery)

• Possibility of extending the incision

• Maximal post operative wound strength

• Minimal post operative discomfort

• Cosmetic effect

The choice of the incision is made by the surgeon with the following considerations:

1. Skin – interrupted stitch, cutting needle is used

2. Subcutaneous (yellow) - not always sutured, round needle

3. Fascia (white) – interrupted stitch, cutting needle

4. Muscle (red) – interrupted stitch

5. Peritoneum (white) – continuous stitch, round needle viscera

****Uterus (dark violet) – continuous stitch, round needle is used

Five Main Layers of Abdominal Cavity (SSFMPU)

Suture

Malignant Hyperthermia

• A rare reaction to anesthetic inhalants (notably sevoflurane, enflurane, isoflurane, and desflurane) and muscle relaxant, succinylcholine

• Caused by abnormal and excessive intracellular accumulations of calcium with resulting hypermetabolism, increased muscle contractions, and elevated body temperature

IV dantrolene sodium (Dantrium)

Malignant Hyperthermia treatment consists of discontinuing the anesthetic inhalant, administration of ______, and applying cooling techniques (e.g. cooling blanket, iced saline lavage)

1. Classify the client’s physical status for anesthesia

• mild disturbances like mild cardiac disease, mild diabetis mellitus

• moribund with little chance of survival like rupture aortic aneurysm

2. Assess the client’s record for appropriate documentation:

• current signed consent form

3. Specifically ask the client about any known allergies.

4. Verify client identification & that the correct surgery is scheduled.

5. Assess for special surgical considerations and precautions

• locations where an electric grounding plate can be safely placed on the client

• avoiding areas where metal or a prosthesis is present

• shielding with a lead apron if radiation is involved if the client is pregnant

6. Assess the client’s risk for accidental hypothermia or malignant hyperthermia during anesthesia administration and surgery

Assessment (SDASSH)

1. Risk for fluid volume deficit or excess

2. Risk for hypothermia or hyperthermia

3. Risk for infection

4. Risk for altered tissue perfusion cardiac, respiratory and peripheral

5. Risk for injury

Nursing Diagnosis
