Standard Green tea extract powder insulin therapy consists of an initial intravenous Diabetes-friendly foods of Emergency protocols for DKA in hospitals.
In clinical situations in which continuous prootcols insulin Anti-inflammatory supplements be DAK, the recommended initial insulin dose is 0. Subsequently, regular insulin should be given in Inflammation and cancer risk dosage of 0.
If the blood glucose concentration does not fall by 50 to 70 mg per dL 2. Either of these treatments should be continued until the blood glucose level falls by 50 to 70 mg per dL.
Low-dose insulin therapy typically produces a linear fall in the glucose concentration of 50 to 70 mg per dL per hour. More rapid correction of hyperglycemia should be avoided because it may increase the risk of cerebral edema. This dreaded treatment complication occurs in approximately 1 percent of children with diabetic ketoacidosis.
Cerebral edema is associated with a mortality rate of up to 70 percent. When a blood glucose concentration of mg per dL has been achieved, the continuous or hourly insulin dosage can be reduced to 0.
The insulin and fluid regimens are continued until ketoacidosis is controlled. This requires the achievement of at least two of these acid-base parameters: a serum bicarbonate concentration of greater than 18 mEq per L, a venous pH of 7.
Although the typical potassium deficit in diabetic ketoacidosis is to mEq to mmolmost patients are hyperkalemic at the time of diagnosis because of the effects of insulinopenia, hyperosmolality and acidemia.
One protocol entails using insulin and intravenous fluids until the serum potassium concentration is less than 5. At this time, potassium chloride is added to intravenous fluids in the amount of 20 to 40 mEq per L.
The exact amount of potassium that is administered depends on the serum potassium concentration. When the serum potassium level is less than 3.
If the serum potassium is greater than 3. The goal is to maintain the serum potassium concentration in the range of 4 to 5 mEq per L 4 to 5 mmol per L. In general, supplemental bicarbonate therapy is no longer recommended for patients with diabetic ketoacidosis, because the plasma bicarbonate concentration increases with insulin therapy.
Retrospective reviews and prospective randomized studies have failed to identify changes in morbidity or mortality with sodium bicarbonate therapy in patients who presented with a pH of 6.
Therefore, the use of bicarbonate in a patient with a pH greater than 7. Furthermore, bicarbonate therapy carries some risks, including hypokalemia with overly rapid administration, paradoxic cerebrospinal fluid acidosis and hypoxia. Some authorities, however, recommend bicarbonate administration when the pH is less than 7.
If bicarbonate is used, it should be given as a nearly isotonic solution, which can be approximated by the addition of one ampule of sodium bicarbonate in mL of sterile water. The bicarbonate solution is administered over a one-hour period.
A small percentage of patients who have diabetic ketoacidosis present with metabolic acidosis and a normal anion gap. Therefore, they have fewer ketones available for the regeneration of bicarbonate during insulin administration.
Osmotic diuresis leads to increased urinary phosphate losses. During insulin therapy, phosphate reenters the intracellular compartment, leading to mild to moderate reductions in the serum phosphate concentration. Adverse complications of hypophosphatemia are uncommon and occur primarily in patients with severe hypophosphatemia a serum phosphate concentration of less than 1.
Prospective studies have indicated no clinical benefit for phosphate replacement in the treatment of diabetic ketoacidosis, and excessive phosphate replacement may contribute to hypocalcemia and soft tissue metastatic calcification.
One protocol is to administer two thirds of the potassium as potassium chloride and one third as potassium phosphate. The use of phosphate for this purpose reduces the chloride load that might contribute to hyperchloremic acidosis and decreases the likelihood that the patient will develop severe hypophosphatemia during insulin therapy.
When diabetic ketoacidosis has been controlled, subcutaneous insulin therapy can be started. The half-life of regular insulin is less than 10 minutes. Therefore, to avoid relapse of diabetic ketoacidosis, the first subcutaneous dose of regular insulin should be given at least one hour before intravenous insulin is discontinued.
In patients who are unable to eat, 5 percent dextrose in hypotonic saline solution is continued at a rate of to mL per hour. Blood glucose levels are monitored every four hours, and regular insulin is given subcutaneously every four hours using a sliding scale Figure 2.
When patients are able to eat, multidose subcutaneous therapy with both regular short-acting and intermediate-acting insulin may be given. In patients with newly diagnosed diabetes, an initial total insulin dosage of 0.
A typical regimen is two thirds of the total daily dosage before breakfast and one third of the total daily dosage before dinner, with the insulin doses consisting of two-thirds NPH intermediate-acting insulin and one-third regular short-acting insulin.
Patients with known diabetes can typically be given the dosage they were receiving before the onset of diabetic ketoacidosis.
Symptomatic cerebral edema occurs primarily in pediatric patients, particularly those with newly diagnosed diabetes. No single factor predictive for cerebral edema has yet been identified. As noted previously, however, overly rapid rehydration or overcorrection of hyperglycemia appears to increase the risk of cerebral edema.
Onset of headache or mental status changes during therapy should lead to consideration of this complication. Intravenous mannitol in a dosage of 1 to 2 g per kg given over 15 minutes is the mainstay of therapy.
Prompt involvement of a critical care specialist is prudent. Adult respiratory distress syndrome ARDS is a rare but potentially fatal complication of the treatment of diabetic ketoacidosis.
Patients with an increased alveolar to arterial oxygen gradient AaO2 and patients with pulmonary rales on physical examination may be at increased risk for ARDS. Monitoring of oxygen saturation with pulse oximetry may assist in the management of such patients.
Hyperchloremic metabolic acidosis with a normal anion gap typically persists after the resolution of ketonemia. This acidosis has no adverse clinical effects and is gradually corrected over the subsequent 24 to 48 hours by enhanced renal acid excretion.
No randomized prospective studies have evaluated the optimal site of care for patients with diabetic ketoacidosis. The response to initial therapy in the emergency department can be used as a guideline for choosing the most appropriate hospital site i.
Admission to a step-down or intensive care unit should be considered for patients with hypotension or oliguria refractory to initial rehydration and for patients with mental obtundation or coma with hyperosmolality total osmolality of greater than mOsm per kg of water.
Most patients can be treated in step-down units or on general medical wards in which staff members have been trained in on-site blood glucose monitoring and continuous intravenous insulin administration.
Milder forms of diabetic ketoacidosis can be treated in the emergency department using the same treatment guidelines described in this review. Successful outpatient therapy requires the absence of severe intercurrent illness, an alert patient who is able to resume oral intake and the presence of mild diabetic ketoacidosis pH of greater than 7.
With the use of standardized written treatment guidelines and flow sheets for monitoring therapeutic response, the mortality rate for patients with diabetic ketoacidosis is now less than 5 percent.
These outcomes have not been altered by the specialty of the primary treating physicians e. An educational program should include sick-day management instructions i. Patients should not discontinue insulin therapy when they are ill, and they should contact their physician early in the course of illness.
Indications for hospitalization include greater than 5 percent loss of body weight, respiration rate of greater than 35 per minute, intractable elevation of blood glucose concentrations, change in mental status, uncontrolled fever and unresolved nausea and vomiting.

Assessment History and examination are directed towards potential precipitants, assessment of severity, and detecting complications of DKA. Assessment of Dehydration Weigh child — compare to recent weight if available. Caution The degree of dehydration is often over-estimated in DKA, this may be compounded by peripheral shutdown due to acidosis. Excessive fluid replacement may increase the risk of cerebral oedema. Collect these bloods with initial blood sampling if practical. Please handover to admitting team if not done Urine Dipstick for ketones, glucose and FWT Culture if clinical suspicion of UTI Consider ECG if potassium results will be delayed Once DKA is confirmed, the following biochemical monitoring should be put in place to guide ongoing management. Consider inserting an NGT to prevent aspiration Keep nil by mouth until child is alert and preferably until acidosis resolves. Children can be given ice to suck on for comfort Insert second IVC to use as a blood sampling line, take initial diagnostic bloods if not drawn with initial IVC insertion Supplemental oxygen for children with severe circulatory impairment or shock Cardiac monitoring — for assessment of ECG changes related to potassium levels hyperkalaemia: peaked T waves, widened QRS, hypokalaemia: flattened or inverted T waves, ST depression, PR prolongation. See ECG Interpretation Consider antibiotics for febrile children after obtaining appropriate cultures Consider urinary catheter for children who are unconscious to allow strict monitoring of fluid balance. This should be followed by a reassessment Acidosis results in poor peripheral perfusion so use central capillary refill with vital signs to assess response to fluids Initial Fluid Replacement Commence rehydration with isotonic fluid eg 0. Children can be given ice to suck on for comfort. The sodium chloride content should be at least 0.

Emergency protocols for DKA in hospitals -
Discuss this with the senior doctor— these children can be very difficult to manage. Shock is defined by the APLS definition of tachycardia, prolonged central capillary refill, poor peripheral pulses and hypotension though this is a late sign of shock.
It is not just poor peripheral perfusion. Cerebral perfusion is dependent on both blood pressure and intracranial pressure cerebral perfusion pressure. Hypotension will increase the risk of brain injury.
Other investigations should be done only if indicated e. CXR, CSF, throat swab, blood cultures, urinalysis, culture and sensitivity etc. a raised white blood cell count is common in DKA and does not necessarily indicate infection. Assess and record the follow parameters in the notes so that comparisons can be made by others later:.
Conscious Level: Institute hourly neurological observations including Glasgow Coma Score and whether or not drowsy on admission. If reduced conscious level on admission, or there is any subsequent deterioration:.
Weigh patient: If this is not possible because of the clinical condition, use the most recent clinic weight. Intravenous or oral fluids that have been given at another hospital should be factored into the assessment and calculation of fluid deficit and replacement needs.
Add calculated maintenance for 48 hours and estimated deficit then subtract amount already given as resuscitation fluid to give total evenly over 48 hours.
A calculator tool using these formulae is available here: DKA Fluid Calculator. Once a child has been resuscitated, potassium should be commenced immediately with rehydration fluid unless anuria present.
Potassium replacement therapy is required for treatment of DKA because there will be a total body deficit of potassium and correction of the acidosis in the absence of potassium therapy will usually rapidly result in hypokalaemia.
Although patients may have hyperkalaemia, hypokalaemia or normokalaemia at presentation there is always massive depletion of total body potassium. Levels in the blood will fall once insulin is commenced. Bicarbonate administration is not routinely recommended as it may cause paradoxical CNS acidosis.
Continuing acidosis indicates either insufficient fluid or, more likely, inadequate insulin replacement. In rare circumstances some extremely sick children may benefit from cautious administration of bicarbonate. This should only be done in discussion with PCC Consultant.
Measured serum sodium is decreased by the dilutional effect of the hyperglycaemia. This document can be made available in alternative formats on request for a person with a disability.

Aim This protocol outlines the assessment and management of Diabetic Ketoacidosis DKA in children and adolescents years and is to be used for Emergency Department ED and inpatient management of DKA.
Background DKA is characterised by the triad of hyperglycaemia, metabolic acidosis and increased total body ketone concentration.
DKA is life threatening and requires immediate treatment. Assessment 1. Consult on-call Paediatric Endocrinologist and PCC if considering PCC admission. Shocked or haemodynamically unstable patients 1.
General Resuscitation Airway Ensure that the airway is patent. If the child is comatose with an obstructed airway,provide airway support e. airway manoeuvres, Guedel airway or endotracheal tube.
Consult Paediatric Critical Care specialist if the patient has a reduced level of consciousness and is unable to protect their airway.
Breathing Give oxygen by face-mask. Circulation Measure blood pressure and heart rate and capillary refill time Cardiac monitor for T waves peaked in hyperkalaemia. Insert two IV cannulas for resuscitation and blood sampling see below.
