Term
WHAT IS THE PROCESS OF CLINICAL ASSESSMENT THAT PRECEDED THE DELIVERY OF ANESTHESIA CARE FOR SURGERY AND NOR NON-SURGICAL PROCEDURES? WHAT TYPES OF PATIENTS RECEIVE THIS?
Definition
PREOPERATIVE ASSESSMENT. ANYONE WHO RECEIVES ANESTHESIA GETS A PREOP EVAL.
Term
WHAT IS THE GOAL OF THE PREOP EVAL?
Definition
TO OBTAIN PERTINENT INFO REGARDING THE PATIENT'S CURRENT AND PAST MEDICAL HX AND TO FORMULATE AN ASSESSMENT OF THE PATIENTS INTRAOPERATIVE RISKS.
Term
INADEQUATE PREOPERATIVE PLANNING AND INCOMPLETE PATIENT PREPARATION ARE COMMONLY ASSOCIATED WITH WHAT?
Definition
ANESTHETIC COMPLICATIONS. PREOPERATIVE EVALUATION GUISED THE ANESTHETIC PLAN.
Term
WHAT SHOULD YOU INFORM THE PATIENT DURING THE PREOP EVAL ABOUT?
Definition
INFORM THE PATIENT OF THE ANESTHETIC PLAN. ALSO INFORM THEM OF THE RISKS ASSOCIATED WITH ANESTHESIA
Term
THE PURPOSE OF THE PREOP EVAL IS TO IDENTIFY PATIENTS WHOSE OUTCOMES WILL LIKELY BE IMPROVED BY IMPLEMENTATION AT A SPECIFIC MEDICAL TREATMENT. GIVE AN EXAMPLE.
Definition
A DIABETIC PATIENT IN WHICH INSULIN IS NEEDED TO CORRECT HYPERGLYCEMIA.
Term
WHAT IS ONE OF THE MOST IMPORTANT THINGS TO INFORM PATIENTS IN PREOP EVAL?
Definition
INFORM OF THE RISKS OF ANESTHESIA.
Term
HOW MANY SIGNATURES DO YOU NEED FOR EMERGENCY CONSENT?
Definition
2 PHYSICAN SIGNATURES. A CRNA DOESN'T COUNT.

WHAT SHOULD BE ASSESSED IN EVERY PATIENT DURING THE PREOP EVAL?
Definition
AIRWAY, LUNGS, AND HEART
Term
WHAT PROVIDES THE BASIS FOR AND DIRECTION OF THE PATIENT INTERVIEW AND ASSESSMENT?
Definition
A CHART REVIEW
Term
WHAT 5 TYPES OF HISTORIES NEED TO BE TAKEN IN THE PREOP EVAL?
Definition
MEDICAL HX, SURGICAL HX, DRUG HX, ANESTHETIC HX, SOCIAL HX
Term
WHAT IS THE FORMULA FOR PACK YEARS? WHAT # OF PACK YEARS SMOKING EQUATES TO AN INCREASED RISK OF PERIOPERTIVE COMPLICATIONS?
Definition
PACK YEARS= NUMBER OF PACKS PER DAY MULTIPLIED BY NUMBER OF YEARS. 20 PACK YEARS ARE ASSOCIATED WITH INCREASE RISKS

Definition
AN AIRWAY ASSESSMENT
Term
PREOPERATIVE LAB IS NOT RECOMMENDED IN ALL PATIENTS, WHY?
Definition
IT IS EXPENSIVE. NOT RECOMMENDED WHEN PATIENTS ARE FIT AN ASYMPTOMATIC. THE LABS SHOULD BE GUIDED BY H&P. A H&H SHOULD BE DRAWN FOR ANY PATIENT WITH INCREASE RISK OF SIGNIFICANT BLOOD LOSS.

Definition
7
Term
DESCRIBE CLASS I CLASSIFICATION.
Definition
WHEN THERE IS NO ORGANIC, PHYSIOLOGIC, BIOCHEMICAL, OR PSYCHIATRIC DISTURBANCE. THESE ARE HEALTHY PATIENTS EXCEPT FOR THE CONDITION THAT HAS NECESSITATED SURGERY.
Term
WHAT DOES THE ASA CLASSIFICATION REPRESENT?
Definition
IT REPRESENTS A REFLECTION OF THE PATIENS PREOP STATUS. ASA CLASSIFICATION REMAINS INDEPENDENT ON THE PROPOSED SURGICAL PROCEDURE. WHICH MEANS A TYPE OF SURGEY DOESN'T PLACE A PT IN A PARTICULAR CLASSIFICATION. IT ALSO DOESN'T REPRESENT AN ESTIMATE OF ANESTHESIA RISK.

IS PULMONARY ASPIRATION OR ASPIRATION PNEUMOITIS CONSIDERED PNEUMONIA?
Definition
NO. ALTHOUGH ASPIRATION CAN LEAD TO PNEUMONIA.
Term
DURING THE EVALUATION PROCESS WHAT SHOULD BE ALWAYS EVALUATE REGARDING INGESTION OF FOOD?
Definition
IDENTIFY PATIENTS WHO ARE AT RISK OF ASPIRATING GASTRIC CONTENTS INTO THE LUNGS AND DEVELOPING ASPIRATION PNEUMONITIS
Term
WHAT ARE THE 3 COMPONENTS OF PULMONARY ASPIRATION?
Definition
1) MOVEMENT OF CONTENTS FROM THE STOMACH TO THE PHARYNX. 2) MOVEMENT OF CONTENTS FROM THE PHARYNX TO THE LUNGS. 3) CONTENTS ARE CAUSTIC AND CAUSE TIDDUE INJURY (ASPIRATION PNEUMONITIS).
Term
DESCRIBE SILENT VERSUS SYMPTOMATIC ASPIRATION.
Definition
SILEN ASPIRATION THERE IS NO DISRUPTION OF PHYSIOLOGIC PARAMETERS. WITH SYMPTOMATIC ASPRIATION LUNG INJURY IS PRESENT. THE PATIENT MAY COUGH AND/OR AUDIBLE WHEEZE.
Term
DEVELOPMENT OF PNEUMONIA, WITH SUBSEQUENT VENTILATION PERFUSION ABNORMALITIES DEPENDS ON WHAT THINGS?
Definition
1) TYPE OF ASPIRATE 2) VOLUME OF ASPIRATE 3) THE PATIENT'S COMORBID CONDITIONS. THE TYPE OF ASPIRATE CAN BE CONTAMINATED, ACIDIV VS ALKALINE, OR PARTICULATE VS NONPARTICULATE.
Term
NAME THE 3 IDENTIFIED ASPIRATION SYNDROMES.
Definition
CHEMICAL PNEUMONITIS (MENDELSON'S SYNDROME, MECHANICAL OBSTRUCTION, OR BACTERIAL INFECTION
Term
WHAT DOES NONACIDIC (ALKALINE) FLUID ASPIRATE DO TO THE LUNGS?
Definition
IT DESTROYS THE SURFACTANT. IT CAUSES ALVEOLAR COLLAPSE AND ATELECTASIS. ALSO CAUSES HYPOXIA. DESTRUCTION OF LUNG ARCHITECTURE AND THE LATE INFLAMMATORY RESPONSE ARE NOT AS GREAT AS IN ACID ASPIRATION.
Term
WHAT DOES THE ACIDIC FLUID ASPIRATE DO?
Definition
DESTRUCTION OF LUNG ARCHITECTURE AND RESULTS WITH LATE INFLAMMATORY RESPONSE.
Term
WHAT MAY HAPPEN WITH PARTICULATE FOOD MATTER ASPIRATE?
Definition
CAUSES BOTH PHYSICAL OBSTRUCTION OF THE AIRWAY AND A LATER INFLAMMATORY RESPONSE RELATED TO THE PRESENCE OF A FOREIGN BODY. ALTERNATING AREAS OF ATELECTASIS AND HYPEREXPANSION MAY OCCUR. IF ACID IS MIXED WITH THE PARTICULATE MATTER, DAMAGE IS OFTEN GREATER AND THE CLINICAL PICTURE WORSE.
Term
WILL THE PT BECOME HYPOXIC AND HYPERCAPNIC DIRECTLY AFTER PARTICULATE FOOD MATTER ASPIRATE?
Definition
THE END RESULT IS HYPOXIA AND HYPERCAPNIA ALTHOUGH AFTER ASPIRATION PTS BECOME TACHYPNEIC WHICH CAUSES HYPOCAPNIA. THEREFORE PTS BECOME HYPOCAPNIA PRIOR TO HYPERCAPNIA.

ASPIRATION OF SOLID FOOD CAUSING LARYNGEAL OR BRONCHIAL OBSTRUCTION. OR ASPIRATION RESULTING IN DIRECT ACID INJURY TO THE LUNG AND PRODUCES THE "ASTHMALIKE" SYNDROME KNOWN AS ASPIRATION PNEUMONITIS. THE RESUL FROM PREEXISTING DISEASE, AIRWAY MANIPULATION, COMPROMISE OF PROTECTIVE REFLEXES.
Term
IS EVERY ASPIRATION PNEUMONITIS ASSOCIATED WITH PNEUMONIA?
Definition
NO
Term
DESCRIBE ASPIRATION PNEUMONITIS.
Definition
A CHEMICAL INJURY. INGESTION OF HIGHLY ACIDIC OR PARTICULATE ASPIRATE MAY CAUSE SEVERE RESPIRATORY DAMAGE WITHOUT AN INFECTIONS COMPONENT. MAY DEVELOP PNEUMONIA OVER TIME DUE TO THE SEVERITY OF THE INJURY AND PROLONGED RESPIRATORY SUPPORT.
Term
WHAT IS THE MOST COMMON CAUSE OF ASPIRATION PNEUMONITIS? WHEN IS IT THE GREATEST? WHAT 3 THINGS ARE IT CHARACTERIZED BY?
Definition
OCCURS WHEN NORMAL PROTECTIVE REFLEXES (SWALLOWING, COUGHING, GAGGING) FAIL. MOST COMMON SETING FOR DEPRESSION OF REFLEX PROTECION ARE THE INDUCTION AND EMERGENCE PHASES OF ANESTHESIA. IT IS CHARACTERIZED BY pH, VOLUME, AND GASTRIC MATERIAL ASPIRATED.

WHAT HAPPENS WITH GASTRIC EMPTYING IN RELATION TO TRAUMA?
Definition
AFTER A TRAUMA GASTIC EMPTYING IS DELAYED. IF YOU ATE AT 12 AND TRAUMA HAPPENED AT 2 THEN YOUR NPO TIME WAS 2 HRS. WITH TRAUMA PATIENTS YOU MAY HAVE A DELAY IN GASTRIC EMPTYING UP TO A WEEK AFTER INJURY.
Term
WHAT TYPES OF PRESSURES CAUSE ACTIVE VOMITING OR GAGGING?
Definition
SUDDEN ONSET OF HIGH INTRAGASTRIC PRESSURE IS ASSOCIATED WITH RELAXATION OF BOTH THE LOWER AND UPPER ESOPHAGEAL SPHINCTER MECHANISMS.
Term

Definition
4-6
Term
DESCRIBE GASTRIC EMPTYING RATES IN OBESE PATIENTS.
Definition
OBESE PATIENTS HAVE THE SAME GASTRIC EMPTYING RATE AS NONOBESE PATIENTS FOR LIQUIDS. SOLIDS EMPTYING MAY ACTUALLY BE FASTER IN OBESE THAN NONOBESE PATIENTS.
Term
HOW DOES PROGESTERONE MAKE A PT AT RISK FOR ASPIRATION?
Definition
PROGESTERONE CAUSES RELAXATION OF THE GES AND IMPAIRS GASTRIC EMPTYING; DECREASE IN LES TONE. EVEN IF THEY ARE ONLY A FEW WEEKS PREGNANT THEY ARE STILL AT RISK FOR ASPIRATION R/T INCREASE IN PROGESTERONE.
Term
WHAT AGE POPULATION IS AT RISK FOR ASPIRATION?
Definition
EXTREMES IN AGE LIKE NEONATES, PREMIE BABIES, AND THE ELDERLY
Term
NAME THE 4 STAGES WHEN YOU ASPIRATE.
Definition
1) ASPIRATED SUBSTANCE CAUSES IMMEDIATE DAMAGE TO THE LUNG RESULTING IN TISSUE DAMAGE. 2) PARASYMPATHETIC RESPONSE THAT LEADS TO AIRWAY CLOSURE AND A DECREASE IN LUNG COMPLIANCE RESULTING IN ATELECTASIS WITHIN MINUTES. 3) 1-2 HOURS AFTER INJURY, AN INTENSE INFLAMMATORY REACTION OCCURS CHARACTERIZED BY PULMONARY EDEMA AND HEMORRHAGE. 4) 24 HOURS AFTER THE INSULT, SECONDARY INJURIES RESULT FROM DEPOSITS AND NECROSIS OF ALVEOLAR CELLS

Definition
MONITOR AIRWAY PRESSURES
Term
WHAT IS A GOOD AIRWAY PRESSURE TO BE LESS THEN WHEN PERFORMING POSITIVE PRESSURE VENTILATION DURING A MODIFIED RSI?
Definition
<15. IN ORDER TO PREVENT GASTRIC INSUFFLATION, EVERY EFFORT SHOULD BE MADE TO VENTILATE THE LUNGS AT THE LOWEST PRESSURE POSSIBLE.
Term
WHAT TYPE OF PATIENTS TYPICALLY DEVELOP PNEUMONIA AFTER ASPIRATION?
Definition
LESS THAN HALF OF ALL ASPIRATIONS LEAD TO PNEUMONIA, WHICH OCCURS MOST OFTEN IN PATIENTS WHO ASPIRATE INFECTED MATERIAL OR WHO ARE IMMUNOCOMPROMISED.

Definition
2
Term

Definition
INCREASING GASTRIC PH.
Term
WHAT IS THE ONSET AND DURATION OF BICITRA?
Definition
ONSET OCCURS WITHIN 15 MINUTES AND DURATION OF ACTION IS 1-3 HOURS. ALTHOUGH CITRATE PREPARATIONS MAY LAST UP TO 6-7 HOURS, SOME PATIENT WILL ALSO EXPERIENCE A REBOUND INCREASE IN GASTRIC ACID PRODUCTION, SO IF SURGERY IS DELAYED MORE THAN 1 HR AFTER CITRATE ADMINISTRATION, IT MAY BE PRUDENT TO REPEAT THE DOSE.
