Term
Pyrogenic reactions:
Definition
The development of fever and chills often associated with N/V and headache.
Term
Infiltration
Definition
Occurs when the needle becomes dislodged from or pierces the vein or from weak, over-extended stretched veins, permitting fluid to collect in the tissues surrounding the vein. Signs of this complication include: swelling around the insertion site, pain, coldness of the skin under the swelling, loss of IV blood flow. If this occurs, discontinue the infusion and restart it using a sterile needle to another site.
Term
Extravasation
Definition
Fluid being infused escapes from the vein into surrounding tissues. Fluid may have damaged surrounding tissue – possible necrosis if pt receives a vesicant. If this occurs, discontinue the IV infusion and change to a different site. Approved treatment protocols are to be followed and crucial documentation.
Term
Thrombophlebitis
Definition
The formation of a blood clot and inflammation of the vein. If this occurs, discontinue the infusion, and place a warm, moist pack on the area, then report development to the Dr. Signs of this complication include: pt may complain of pain, nurse may note heat, redness, swelling, possible loss of motion in body part.
Term
Pain
Definition
Occurs when irritating drugs such as KCl are being infused, esp, when superficial veins are uses or/and med is infused too rapidly or is inadequately diluted. If this occurs, check for tension, gently move the hub of the needle to see if pain decreases, and/or change the rate of flow, change to larger vein.
Term
Fluid overload:
Definition
An overload of the circulatory system that may be due to the excessive or too rapid infusion of fluid. Most common in children and clients with impaired cardiovascular or renal systems. If this occurs, slow the infusion and call someone to evaluate the patient. Signs of this complication include moist respirations, dyspnea, cough.

The presence of pathogenic microorganisms at the insertion site and possible disseminating
through the vascular access into the bloodstream. If this occurs, call the physician STAT.
Term
    MED calculations and gtts per minute      
Definition
1000 g = 1 kg 1 mL = 15 gtt
1000 mg = 1 mg 1 minim = 1 gtt
1000 ng = 1 mcg 1 t = 60 gtt
1000 mcg = 1 mg 3 t = 1 T
1000 mL= 1 L 1 oz = 2 T
100 mL = 1 dL 1 dram = 50 grains
1 kg = 2.2 lbs

To calculate the flow rate using the ratio and proportion method:
1. Determine the number of ml the client will receive in an hour
2. Determine the number of ml the client will receive in a minute
3. Determine the drops per minute that will equal the number of ml computed in step 2. The drop rate specified for the IV set being used must be considered in this step. The drop is expressed as a ratio of gtt/mL.

Example: The HCP prescribes 3000 mL of D5W IV over a 24 hr period. If the IV set is calibrated to deliver 15 gtt/mL, how many drops must be administered per minute?

Calculate mL/hr 3000 mL = x mL
24 hr 1 hr X = 125 mL/hr

Calculate mL/min 125 mL = x mL
60 min 1 min x = 2 ml/min

Calculate gtt/min 15 gtt = x gtt
1 mL 2 mL/min x = 30 gtt/min

Example: How long will it take to complete an IV infusion of 1.t L of D5W being administered at the rate of 45 gtt/min? The IV set is calibrated to deliver 15 gtt/mL.

1. Determine mL /min being infused: Drop rate of IV set = 15 gtt = 45 gtt
1 ml x mL 15x = 45 X = 3 mL/min

Calculate mL/hr:
3 mL/min X 60 min/hr = 180 mL/hr

Calculate hrs required to administer total volume of solution. If 180 mL are delivered each hr, then how many hrs are required to administer 1500 mL?
180 mL = 1500 mL
1 hr X hr 180 x = 1500 X = 8.3 hr or 8 hr 20 min

Benzodiazepine - antianxiety. Potentiates GABA actions, esp in limbic system, reticular formation. Used for short term management of anxiety, acute alcohol withdrawal, preoperatively for relaxation. Side effects: dizziness, drowsiness, orthostatic hypotension, blurred vision, ECG changes, tachycardia. Nursing considerations: Assess: BP, pulse; hold drug if BP drops 20 mmHg.; Assess blood studies: CBD; blood dyscrasias; hepatic studies – AST, ALT, bilirubin, creatinine, LDH, alk phos; I/O – may indicate renal dysfunction; for ataxia, oversedation in geriatric; mental status; physical dependency; withdrawal symptoms; suicidal tendencies, paradoxic reaction.
Term
Anesthetics administered by inhalationSemiclosed method
Definition
A gas mixture from a reservoir containing the anesthetic is provided through a mask that is connected to it. Gas escapes through valves, preventing rebreathing of air. This can create a hazardous situation.
Term

Anesthetics administered by inhalation

Closed method
Definition
Completely closed system, part of an anesthetic machine that fits over the face of the client. Safer than semi closed method. INH anesthetics may cause side effects such as nausea and vomiting, lower B/P, and alter resp. rate and cardiac output.
Term
Nitrous oxide (Laughing Gas
Definition
most common gaseous anesthetic agent used. Usually administered in combo with O2. Colorless, odorless and nonirritating. Equivalent to 10 mg morphine sulfate. Weak and generally used in combination with another anesthetic. O2 should be used for several minutes after to prevent hypoxia. Cylinders are always blue. Not explosive.
Term
Anesthetics administered by IV injection 
Definition
Generally used for induction of anesthesia before using inhaled agents.
Induction with these agents occurs rapidly (less than 30 sec.) Relative inability to stimulate salivation or emesis. Nonexplosive. Can cause apnea, coughing, hypo/hypertension, laryngospasm and bronchospasm. Difficult to control adverse side effects. Impossible to remove drug from body one it has entered the blood stream. May cause malignant hyperthermia( high fever 104*-105*)
Term
Propofol (Diprivan)
Definition
Usual dosage: Induction- 100-150 mcg/kg/min Maintenance- 50-200 mcg/kg/min Classified as an alkyl phenol Emulsion- need to shake well. Protect from light. Monitor client for apnea bradycardia. A hypnotic effect is produced within 40 sec of rapid IV bolus dose. Anesthesia maintained by administering drug by infusion or intermittent IV bolus injection. Should only be administered into a running IV catheter. Patients wake up quickly and do not remember anything.
Term
Midazolam HCI (Versed)   
Definition
Usual dosage: IV- 0.15-0.35 mg/kg IM- 0.07-0.08 mg/kg Not to be used in pts with open angle glaucoma. Administer drug slowly. Chemically related to Valium. When administered intravenously it induces anesthesia with in 1.5-2.5 minutes. Often given intravenously to produce conscious sedation prior to short diagnostic or endoscopic procedures.
Term
Balanced Anesthesia
Definition
A combination of inhalation & IV medications. Most commonly used practice of administering general anesthesia. Effective and safe especially for elderly clients and those at high risk for pulmonary problems.
Provide analgesia, hypnosis, amnesia, muscle relaxation, and relaxation of neurological reflexes. Preanesthetic medications are used prior to the administration of an anesthetic to facilitate induction of anesthesia and to relieve anxiety and pain.
Term
Sedative-Hypnotics    
Definition
The most common agents used to produce sedation. Midazolam HCI (Versed) Effects include sedative, hypnotic, antianxiety, muscle relaxation, and amnesic effects
Term
Opioid analgesics  
Definition
Commonly used to augment inhalation anesthesia as well as being primary agents in regional anesthesia.
Term
Anticholinergics   
Definition
Belladonna alkaloids. Diminish salivation and can prevent laryngospasm and reflex slowing of the heart during general anesthesia. Must be used with caution in pts with a fever because they depress the sweating mechanism.
Term

Neuromuscular agents   

Definition
Used to relax the jaw and throat muscles immediately following induction so an endotracheal tube can be placed to maintain a patent airway and facilitate alveolar ventilation during surgery. May cause circulatory compromise and respiratory muscle paralysis during the surgery.
Term
Regional Anesthesia      
Definition
Anesthesia Cocaine was one of the first anesthetics to be discovered. These drugs prevent the generation and the conduction of the nerve impulse. Capable of causing CNS stimulation (restlessness, tremors, and clonic convulsions) followed by CNS depression, resp. depression, and death.
Term
Selection of the proper agent should be selected by   
Definition
- Area to be anesthetized. - Agent’s duration of action. - Client’s history of allergies. - Healthcare provider s experience with the drug.
