Drugs
Intense heat/cold
Metabolism
• Stimulation of gluconeogenesis– Amino acids to glucose in liver cells
• Reduction of protein stores in allcells except the liver
– Decreased protein synthesis, increasedcatabolism in muscle
• Mobilization of fat from adiposetissue
Cardiovascular
• Improves vascular tone:– Permissive effect on catecholamine and
vasoactive peptide synthesis.
– Enhances small vessel contractility in response tocatecholamines.
– Reverse adrenergic receptor desensitization.
– Inhibits NO-synthase in vascular endothelial cells.
– Inhibits phospholipase A2 and arachidonic acid.
• Increases contractility or stroke volume.
• Maintains fluid distribution and plasmavolume.Inflammation
Cortisol: Role in Inflammation
• Stabilizes lysosomal membranes
• Decreases permeability ofcapillaries
• Decreases migration of WBCs
• Attenuates SIRS– Reduces production of cytokines
– IL-1, IL-6, TNF-

RIA
• ACTH– CST will vary during illness
– Decreased response to ACTH
• Albumin and CBG
• Protein binding– albumin
– volume of distribution
– hormone levels (i.e. estrogens)
– drugs
• Reduced metabolism– Decreased excretion
– Decreased breakdown
• Increased receptor resistance
• Inflammation
• Free fraction most important
9
• Whether serum free cortisol concentrations arecorrelated better with outcomes such as deathremains speculative.
– Patients with low albumin are sicker and tend todo poorly
– The dose of the ACTH – controversial
– More study is needed with free levels.

• Minimal steroid use
• 56% mortality
The Corticus Trial
• 72 hour time frame
• Excluded patientstreated – over 50%

• Septic shock patients presenting to the ED:– Adequate volume resuscitation– Vasopressor dependency
• Adrenal dysfunction is common in high-risk ED patients.
• 19% incidence of adrenal dysfunction in ED patients.
ACADEMIC EMERGENCY MEDICINE 1999; 6:626–630

• The effects of low or high APACHE II score and early or latehydrocortisone initiation are additive.
• In patients with high APACHE score (= 19), the early initiation ofhydrocortisone increased the survival rate from 19.8% to 41.2% (p= 0.021).
• Likewise, in patients with low APACHE score (< 19), the earlyinitiation of hydrocortisone increased the survival rate from 55.0%to 83.3%.

• Significant interaction between vasopressininfusion and corticosteroid treatment (p<0.008).
• In patients:
–Steroids, NE and vasopressin:
• Mortality - 35.9%
–Norepinephrine alone:
• Mortality - 44.7%, p<0.03

• Patients who did not receive corticosteroids, butvasopressin:– increased mortality was seen compared with norepinephrine
(33.7%vs.21.3%, respectively, p<0.06).
• Patients who received vasopressin infusion:
– corticosteroids significantly increased plasma vasopressinlevels by 33% at 6 hours (p<0.006)
– 67% at 24 hours (p<0.025) compared with patients whodid not receive corticosteroids.
Crit Care Med 2009 Vol.37,No.3
18
• For all trials, regardless of duration of treatment and dose, use ofsupra-physiologic corticosteroids doses did not significantly affectmortality.– Methylprednisolone 30 mg/kg
– Dexamethasone 3-6 mg/kg
• Physiologic doses:– Short course of less than 7 days
– Hydrocortisone <300 mg/day is in.
• Targeting high risk patients:– Treating patients insensitive to catecholamines.
– After adequate volume resuscitation.
– Treat early
• Improved efficacy:– After adequate resuscitation
– Vasopressin
– Treat within 9 hours in severe illness
• Need better laboratory diagnosis:– Cortisol levels and stimulation test are inaccurate

Simplifying Glucose Control
in the ICU
What we know for certain
High blood glucose correlates with severity of illness
High glucose correlates with mortality
Blood sugars >200 mg/dl result in glucosuria
Blood sugars > 200 mg/dl impair wound healing
Blood sugars <40 mg/dl may result in cardiac and brain ischemia
IV insulin is the safest method of administration
Meta-analysis pre-NICE SUGAR
Meta-analysis post-NICE SUGAR
Death more frequent in tight glycemic control
arm
< or = 180 mg/dl
0.5% hypoglycemia
Severe hypoglycemia (<40 mg/dl)
Mortality difference: some studies suggest an increase of nearly 10% in patients with hypoglycemia, controlling for severity of illness
15% verses 25%
2009 American Association of Clinical Endocrinologists and American Diabetes Association consensus statement on the management of inpatient hyperglycemia
In the intensive care unit (ICU), the threshold to start treatment is a BG of <or=180 mg/dL
I.V. insulin is the treatment of choice in critically ill patients because of its rapid onset and offset of action
Once i.v. insulin is started, the BG should be maintained between 140 and 180 mg/ dL
A lower BG target (110-140 mg/dL) may be appropriate in selected patients. Targets of <110 mg/dL or >180 mg/dL are no longer recommended
Special Populations
Myocardial Infarction
Post-CABG
Prolonged mechanical ventilation
Neurological
Goal may be closer to 110 mg/dl
Renal Insufficiency
Insulin algorithm
Blood glucose testing no less frequent than every two hours
Insulin infusion rate should not be stopped when glucose values consistently fall below the glucose target range but above hypoglycemia (should have variable dosing regimens algorithms)
Staff should be knowledgeable or protocol should address anticipated changes in insulin requirement: interruption of nutrition, new renal failure
Should allow for transition to subcutaneous insulin regimen
Insulin algorithm
Continued, steady progress is more important than rapid achievement of goal (remember hypoglycemia is risky)
Should include hypoglycemia order set
Continuous IV Insulin Protocol
See handout : Adult Inpatient IV Insulin Infusion Orders
Goal established at the start
4 hours stability before increasing BG check to 2 hr interval
Start at insulin-sensitive doses (you make about 24 units of insulin every 24 hours
Hypoglycemia algorithm
Anticipated need for increased insulin after meal
Hypoglycemia (nurse-based therapy)
For treatment of BG below 70 mg/dl in a patient with an altered level of consciousness:
administer 25 ml dextrose 50% IV and start IV dextrose
5% in water at 100 ml/h
In a patient with an altered level of consciousness and no available IV access
give glucagon 1 mg IM, limit X 2
Recheck BG and repeat treatment every 15 minutes until blood glucose is 80 mg/dl, X 2-3 readings
Hypoglycemia (nurse-based therapy)For treatment of BG below 70 mg/dl in a patient who is alert and able to eat and drink, administer 15-20 g of rapid acting carbohydrate such as:
one 15-30 g tube of glucose gel
4 ( 4g) glucose tabs
4-6 ounces orange or apple juice
6 ounces “regular” sugar sweetened soda
8 ounces skim milk
For treatment of BG below 70 mg/dl in an alert and awake patient who is NPO or unable to swallow:
administer 20 ml dextrose 50% IV and start IV dextrose
5% in water at 100 ml/h
Emergent Perioperative Hyperglycemia Management
Perioperative complications are higher in patients with hyperglycemia (as evidenced by glucose of 180 mg/dl or greater)
Risk is greater in patients without previous diagnosis of diabetes
Must rule out DKA before surgery to address the electrolyte and acid-base derangements
HHS patients need volume resuscitation before surgery
Realistic goal is 110-180 mg/dl
Emergent Perioperative Hyperglycemia Management
All patients receiving insulin before surgery require insulin in the perioperative period
Surgical performance measure is glucose <180 mg/dl in the 18-24 postoperative period (will likely influence reimbursement)
Frequent blood sugar measurements in an effort to identify glucose > 160 mg/dl, as IV insulin is reasonable at this value
IV insulin is best administered per established safe and efficacious protocol
If patient is not eating, IV insulin is best
Parenteral Nutrition
Provide calories equal to 100-120% estimated basal energy expenditure (Harris-Benedict equation)
Permissive underfeeding for obese patients or marked hyperglycemia/hypertriglyceridemia
Obtain blood glucose before start
Limit dextrose to 150-200 gms on day 1
Parenteral Nutrition
2 glucose values > 150, add 0.1 units of regular insulin per gram of dextrose
If renal failure then 0.05 units per gram
Increase by 0.05 units up to maximum of 0.2 units/gram
Then consider permissive underfeeding
Try not to increase glucose content until glycemic control is achieved
If hypoglycemia occurs: was PN discontinued? Otherwise, decrease by 50%
Tube Feeding
Pts without DM: short acting insulin until tube feeds reach 30-40 ml/hour, especially if there is higher chance for discontinuationGlucose should be checked before each feeding
and no sooner than 4 hours after prior feedingA very reasonable starting point is 1 unit for every
15 gms of carbs, remember you can make orders “responsive” If the 4hour post-feed glucose is greater than 160
mg/dl, then increase by 10-20%
Tube feeding continued
Once tube feeds are greater than 40 ml/hr for at least 12 hours, then consider intermediate acting insulin
Dosed before tube feeds: 1 single dose for 12 hours tube feeds or q 8 hours for continuous tube feeds
0.2-0.4 units/kg is a reasonable starting dose (remember peak will be around 3-5 hours)
What is the most common cause of
hypoglycemia using such an
approach?
Switching to SQ insulin Estimate 24 hour basal insulin requirements of 24 hours using
the last 8 hours requirement X 3, then take 80% If not stable, then be conservative and overlap with the drip Options: give 1/3 dose as NPH Q 8 H
give 1/2 dose as Glargine/Detemir Q 12 Hgive full dose as Glargine/Detemir Q 24 H
Remember overlap IV insulin, 1-3 hours or less if glucose falls below 100 mg/dl
Sliding Scale: 1 U/15 g carbohydrate (insulin sensitive) to 2-3 U/15 g carbohydrate (insulin resistant)
BG Unit of rapid acting insulin

What about the severely insulin resistant ICU patient?
Extreme Insulin Resistance
51 y/o male admitted with fever and probable sepsis secondary to perirectal abscess
Intubated and hypotensive on catecholamine infusion
Outpatient medications unknown at the time of admission
Family members report “diet-controlled diabetes”
Extreme Insulin Resistance
Blood sugar on admission was 678 mg/dl
Blood pressure 69/42, HR 112 bpm
Exam: morbidly obese, +acanthosis nigricans
Insulin per protocol: 29 units regular insulin per protocol
Blood glucose 390 mg/dl
Extreme Insulin Resistance Usually multiple concurrent etiologies
Most often occurs in obese patients (high underlying insulin resistance)
Underlying mechanisms: sympathetic activation, pro-inflammatory cytokines Unrestrained lypolysis
Impaired insulin secretionGlucose productionCortisol secretion
Step-wise approach
Is it really insulin resistance?
Is insulin reaching the patient?
Concurrent with a new bag or syringe of insulin
Infusion connected into maintenance IV or other tubing
Connections tight
Good blood return
Step-wise approach
Is it really insulin resistance?
Underlying electrolyte abnormalities?
Hypercalcemia, Hypocalcemia, Hyperkalemia, Hypomagnesemia
Step-wise approach
Is it really insulin resistance?
Underlying electrolyte abnormalities?
Culprit medications or change in nutrition?
Nutrition and medications Change in nutrition: TPN, Intralipid
New medication: review the medication list
(catecholamines, corticosteroids, propofol, megace, octreotide)
Discuss with pharmacy (which medications can be changed from lipid or glucose emulsion/diluent/)
Extreme insulin resistance
TPN: Add regular insulin to the TPN itself
No more than 50% of the total daily insulin dose
Decreases the risk of hypoglycemia
Steroid-induced hyperglycemia
Major effect 6-8 hours after administration
Results primarily in post-prandial excursion
NPH timed with steroids0.1 units/kg per 10 mg prednisone (or steroid equivalent) up to a maximum of 0.4 units/kg
Lasts 6-8 hours, longer in renal dysfunction
If not at at goal increase next dose by 10-20%

In Hospital Cardiac Arrest
• Extrapolation of the incidence of in-hospital cardiac arrest reported by GWTG suggests that each year 209,000 (quasi CI; 192,000–211,000) people are treated for in-hospital cardiac arrest
• In 2011, survival to discharge was 24.2% (95% CI, 23.5%–24.9%) for patients of any age; 23.9% (95% CI, 23.2%–24.6%) for adults; and 40.2% (95% CI, 34.2%–46.2%) for children (excluding neonates)

In Hospital Cardiac Arrest
• In 2011, 17.6% (95% CI, 17.0%–18.3%) of patients of any age or 17.7% (95% CI, 17.1%–18.4%) of adults and 14.1% (95% CI, 9.8%–18.3%) of children (excluding neonates) had VF or pulseless VT as the first recorded rhythm
• Of these, 43.0% (95% CI, 41.0%–45.0%) of adults and 52.8% (95% CI, 36.5%–69.1%) of children (excluding neonates) survived to discharge

In Hospital Cardiac Arrest• Up to 2/3 of hospital cardiac arrests are
considered preventable (Hodgetts et al. Resuscitation, 2002;54:115-23)
• 118 arrest cases compared with 132 non-arrest controls (Hodgetts et al. Resuscitation, 2002;54:125-131)
• Abnormal respiratory rate (p=0.013)• Abnormal breathing indicator (p<0.001)• Abnormal pulse (p<0.001)• Reduced systolic blood pressure (p<0.001)• Abnormal temperature (p<0.001)• Reduced pulse oximetry (p<0.001)• Chest pain (p<0.001)• Nurse or doctor concern (p<0.001)
• A significant proportion of hospitalized patients experience serious adverse events during their stay.
• These events include cardiac arrest, respiratory failure requiring emergency intubation, unplanned ICU admissions, and death.
• Most of these events are not abrupt but preceded by hours of physiologic deterioration (e.g., 6 to 8 hours) that can recognized (e.g., tachypnea, tachycardia, hypotension, decreased O2
saturation, and changes in mentation).

Critical Access Hospitals and Hospitals (PC.02.01.19, HR.01.05.03, PI.01.01.01)
• PC.02.01.19 The hospital recognizes and responds to changes in a patient's condition. Note: Hospitals are not required to create "rapid response teams" or "medical emergency teams" in order to meet this standard. The existence of these types of teams does not mean that all of the elements of performance are automatically achieved.
• EP #1. The hospital has a process for recognizing and responding as soon as a patient's condition appears to be worsening.

Critical Access Hospitals and Hospitals (PC.02.01.19, HR.01.05.03, PI.01.01.01)
• EP #2. The hospital develops written criteria describing early warning signs of a change or deterioration in a patient's condition and when to seek further assistance
• EP #3. Based on the hospital's early warning criteria, staff seek additional assistance when they have concerns about a patient's condition.
• EP #4. The hospital informs the patient and family how to seek assistance when they have concerns about a patient's condition.
• Organizations like the American Heart Association, Institute for Healthcare Improvement, and Society for Critical Care Medicine are promulgating some form of RRS, and many hospitals are implementing them.
• Although the structure may vary, they all rely on the prompt identification and treatment of acutely critically ill hospitalized patients.
RAPID RESPONSE SYSTEMS(Critical Care Medicine 2006;34:2463–2478)
• The data about effectiveness of RRS has been controversial:
• Several single-center studies have shown a reduction in the rate of cardiac arrests by using before-and-after RRS implementation studies.
• However, meta-analyses have questioned whether there are benefits and have suggested that further research is required (Chan PS et al. Arch Intern Med 2010;170:18-26; McGaughey J et al. Cochrane Database of Systemic Reviews 2007;3:CD005529.9)
RAPID RESPONSE SYSTEMS
In Hospital Cardiac Arrest
• Before-after evaluation of implementing an early warning score system (Drower et al. N Z Med J. 2013 Nov 1;126(1385):26-34)
• 600-bed tertiary teaching hospital in New Zealand during the two 12-month periods between March 2009 and March 2011
• 168 cardiac arrests during the 24 month period • The incidence cardiac arrests dropped from 4.67 to 2.91 per
1000 admissions (mean difference 1.77, 95%CI 0.59-2.94)
• The number of cardiac arrests dropped from 8.5 to 5.5 arrests per month (mean difference 3.0, 95%CI 0.78-5.22)
• Introduction of an EWS system in addition to an existing cardiac arrest team response decreased the incidence of in-hospital cardiac arrests in a tertiary hospital in New Zealand
J Community Hosp Intern Med Perspect. 2015 Apr 1;5(2):26716. doi: 10.3402/jchimp.v5.26716. eCollection2015.Modified Early Warning System improves patient safety and clinical outcomes in an academic community hospital.Mathukia C1, Fan W1, Vadyak K1, Biege C1, Krishnamurthy M2.Author informationAbstractBACKGROUND AND OBJECTIVE:Severe adverse events such as cardiac arrest and death are often heralded by abnormal vital signs hours before the event. This necessitates an organized track and trigger approach of early recognition and response to subtle changes in a patient's condition. The Modified Early Warning System (MEWS) is one of such systems that use temperature, blood pressure, pulse, respiratory rate, and level of consciousness with each progressive higher score triggering an action. Root cause analysis for mortalities in our institute has led to the implementation of MEWS in an effort to improve patient outcomes. Here we discuss our experience and the impact of MEWS implementation on patient care at our community academic hospital.METHODS:MEWS was implemented in a protocolized manner in June 2013. The following data were collected from non-ICU wards on a monthly basis from January 2010 to June 2014: 1) number of rapid response teams (RRTs) per 100 patient-days (100PD); 2) number of cardiopulmonary arrests 'Code Blue' per 100PD; and 3) result of each RRT and Code Blue (RRT progressed to Code Blue, higher level of care, ICU transfer, etc.). Overall inpatient mortality data were also analyzed.RESULTS:Since the implementation of MEWS, the number of RRT has increased from 0.24 per 100PD in 2011 to 0.38 per 100PD in 2013, and 0.48 per 100PD in 2014. The percentage of RRTs that progressed to Code Blue, an indicator of poor outcome of RRT, has been decreasing. In contrast, the numbers of Code Blue in non-ICU floors has been progressively decreasing from 0.05 per 100PD in 2011 to 0.02 per 100PD in 2013 and 2014. These improved clinical outcomes are associated with a decline of overall inpatient mortality rate from 2.3% in 2011 to 1.5% in 2013 and 1.2% in 2014.CONCLUSIONS:Implementation of MEWS in our institute has led to higher rapid response system utilization but lower cardiopulmonary arrest events; this is associated with a lower mortality rate, and improved patient safety and clinical outcomes. We recommend the widespread use of MEWS to improve patient outcomes.

AFFERENT LIMB AT FHCC(Recognition and Activation)
A dedicated red phone rings in the CCU
• An ICU nurse receives the call, collects basic information, and passes the call to the ICU resident.
• The ICU resident assesses the information given and provides guidance:
• Transfer patient to ED
• Assess at bedside
• Ask for more information
• Request to CODE aactivation
EFERENT LIMB AT FHCC(Response)
RAPID RESPONSE SYSTEM at FHCC
• The efferent limb works well without having a “dedicated team” using instead the ICU and ED resources.
• For calls originating outside the main hospital, the typical response is to instruct transfer of the patient to the ED.
• In 60% or more of the calls the patient is moved to a higher level of care.
• The ED is an safe and effective place for rapid evaluation and triage of a patient suffering physiological deterioration, and circumvents treatment delays inherent to deploying and ill equipped team to remote areas
• For call originating in med-surg units, proper response is bedside assessment to determine whether direct ICU admission is warranted
RAPID RESPONSE SYSTEM at FHCC
• A RRS call is not a CODE call.
• A RRS call implies there is physiological deterioration but at a pace that allows a brief discussion to initiate a response that is commensurate to the clinical situation.
• RRS also enables reductions in false codes.
• The option for activating the CODEremains available through the process (~1%)

Resuscitative CODES refers to CODES in which a resuscitation intervention was used (i.e., chest compressions, defibrillation). Non-resuscitative CODES refers to deployment of the CODE team but without delivering a resuscitation intervention and considered appropriate when the event could have placed the patient at risk of a life-threatening event or was perceived at such by the caller.
• More than 200,000 patients suffer cardiac arrest in the hospital every year in the United States
• Most of cardiac arrest (~2/3) occur after progressive physiological deterioration over hours (even days) and are potentially preventable
• Rapid Response Systems can recognize and intervene to avert preventable in-hospital deaths; with the recognition arm being the most critical
• In the event of a cardiac arrest, resuscitation efforts can benefit from enhanced monitoring capabilities guiding the effort based on physiological measurements, and also benefit from available therapeutic capabilities
