HAI insulin dose calculation correction factor sliding scale high blood sugar 318 400 580 mg/dL Lantus initiation dose

Important clinical disclaimer: Insulin dosing must always be individualized and prescribed by a qualified physician. The calculations below are standard reference guidelines - they are NOT a substitute for clinical judgment. Patient weight, renal function, comorbidities, oral intake, and concurrent medications all affect the final dose.

Blood Sugar Summary

Time	BSL (mg/dL)	Status
Fasting	318	Severely elevated
Post-prandial (PP)	400	Severely elevated
Night	580	Critically elevated

Target blood glucose: ~100-140 mg/dL (fasting), ~140-180 mg/dL (post-meal)

Step 1: Estimate Total Daily Insulin (TDI) Requirement

Weight-based starting point (standard for uncontrolled Type 2 DM):

If patient weight is unknown, the average starting TDI for significantly elevated sugars is 0.5 units/kg/day
For a typical 60 kg patient: TDI = 0.5 × 60 = 30 units/day
For a 70 kg patient: TDI = 0.5 × 70 = 35 units/day
For an 80 kg patient: TDI = 0.5 × 80 = 40 units/day

Split: 50% basal (Lantus at night) + 50% bolus (HAI/Regular before meals)

Step 2: HAI (Human Actrapid / Regular Insulin) - Mealtime + Correction Doses

Pre-Meal Bolus Dose

The bolus 50% of TDI is divided equally among 3 meals:

Patient Weight	TDI	HAI per meal (50% TDI ÷ 3)
60 kg	30 u	~5 units per meal
70 kg	35 u	~6 units per meal
80 kg	40 u	~6-7 units per meal

Correction Factor (Rule of 1500 for Regular/HAI insulin)

Correction Factor (CF) = 1500 ÷ TDI

Patient Weight	TDI	CF (1500÷TDI)
60 kg	30 u	1 unit drops BSL by ~50 mg/dL
70 kg	35 u	1 unit drops BSL by ~43 mg/dL
80 kg	40 u	1 unit drops BSL by ~37 mg/dL

Correction Doses Based on Actual BSL (Target = 120 mg/dL, CF = 50 mg/dL per unit example):

Correction dose = (Actual BSL - Target BSL) ÷ CF

Fasting BSL = 318 mg/dL:

Excess = 318 - 120 = 198 mg/dL
Correction = 198 ÷ 50 = ~4 units HAI (in addition to mealtime dose)
Total morning dose = ~5 (meal) + 4 (correction) = 9 units HAI (for 60 kg patient)

PP BSL = 400 mg/dL (if given as afternoon/evening correction):

Excess = 400 - 140 = 260 mg/dL
Correction = 260 ÷ 50 = ~5 units HAI
Total dose = ~5 (meal) + 5 (correction) = 10 units HAI

Practical HAI sliding scale for these sugar levels:

Blood Sugar (mg/dL)	HAI Correction Dose
< 150	0 units
150 - 200	2 units
201 - 250	4 units
251 - 300	6 units
301 - 350	8 units
351 - 400	10 units
401 - 450	12 units
> 450	14 units + call physician

This is a moderate-intensity scale appropriate for BSL > 300 mg/dL. Add mealtime bolus on top of correction if given before a meal.

Step 3: Lantus (Glargine) - Night Dose

Starting basal dose = 0.1-0.2 units/kg/day OR 10 units at bedtime (standard initiation)

For uncontrolled sugars this high, many guidelines start at 0.2 units/kg or 50% of TDI:

Patient Weight	Starting Lantus (0.2 u/kg)	Alternative (50% TDI)
60 kg	12 units at bedtime	15 units
70 kg	14 units at bedtime	17-18 units
80 kg	16 units at bedtime	20 units

Night BSL = 580 mg/dL - this is a critically elevated reading. Lantus alone will NOT acutely lower this. For a BSL of 580 at night:

Give HAI correction NOW: (580 - 120) ÷ 50 = ~9 units HAI SC as correction
Then give Lantus 10-16 units at bedtime as the basal dose
Recheck BSL in 2-3 hours
If BSL > 400 with symptoms (vomiting, rapid breathing), evaluate for DKA/HHS urgently

Summary Table

Insulin	Dose	Timing
HAI (Regular)	5-7 units + correction	Before each meal (3x/day)
HAI correction (fasting 318)	+4 units	With morning meal dose
HAI correction (PP 400)	+5 units	After-meal correction
HAI emergency (night 580)	~9 units	Immediately, then recheck in 2h
Lantus (Glargine)	10-16 units	Once at bedtime (10 PM)

Titration of Lantus (Standard "3-3 Rule")

Increase Lantus by 2 units every 3 days if fasting BSL remains > 130 mg/dL, until target is reached. Maximum uptitration is guided by fasting values:

Fasting BSL	Lantus Adjustment
> 180 mg/dL	Increase by 4 units
140-180 mg/dL	Increase by 2 units
110-139 mg/dL	Increase by 1 unit
80-110 mg/dL	No change (target reached)
< 80 mg/dL	Decrease by 2-4 units

Key points:

Patient weight is needed for precise dosing - share it for exact calculation
Night BSL of 580 needs urgent attention - rule out DKA/HHS before just adding insulin
HAI should be given 30 minutes before meals (it is NOT a rapid-acting analogue)
These are starting doses - adjust based on response over 3-7 days
Hypoglycemia risk increases significantly with these correction doses - monitor closely

Wt 28kg

Weight 28 kg — this is a child or a very underweight adult. This changes the calculation significantly and requires extra caution.

Insulin Dose Calculation for Weight = 28 kg

Total Daily Insulin (TDI)

For an uncontrolled diabetic with very high sugars, starting dose = 0.5 units/kg/day

TDI = 0.5 × 28 = 14 units/day

Split 50/50:

Basal (Lantus) = 7 units at night
Bolus (HAI) = 7 units total ÷ 3 meals = ~2 units per meal

Correction Factor (CF)

Using Rule of 1500 for Regular/HAI insulin:

CF = 1500 ÷ TDI = 1500 ÷ 14 = ~107 mg/dL per unit

Rounded practically: 1 unit of HAI drops BSL by ~100 mg/dL

Target BSL = 120 mg/dL

HAI Dose - Meal by Meal

Morning (Fasting BSL = 318 mg/dL)

Correction = (318 - 120) ÷ 100 = ~2 units
Mealtime bolus = 2 units
Total morning HAI = 4 units (give 30 min before breakfast)

Afternoon/Evening (PP BSL = 400 mg/dL)

Correction = (400 - 140) ÷ 100 = ~2-3 units
Mealtime bolus = 2 units
Total evening HAI = 4-5 units (give 30 min before dinner)

Night (BSL = 580 mg/dL) - URGENT

This reading needs immediate correction before giving Lantus
Correction = (580 - 120) ÷ 100 = ~4-5 units HAI SC now
Recheck BSL in 2 hours
Then give Lantus once BSL is coming down

⚠️ BSL 580 in a 28 kg patient (likely a child) - rule out DKA urgently: check for ketones, rapid breathing (Kussmaul), vomiting, altered sensorium. If DKA present, standard IV insulin protocol takes priority over SC insulin.

Lantus (Glargine) Night Dose

Lantus = 0.25 units/kg for pediatric/underweight initiation (more conservative) = 0.25 × 28 = 7 units at bedtime

Formula	Dose
50% of TDI (14 u)	7 units
0.25 u/kg	7 units
Recommended Lantus	7 units SC at 10 PM

Complete Summary

Insulin	Dose	Timing
HAI (Regular)	4 units	30 min before breakfast
HAI (Regular)	2 units	30 min before lunch
HAI (Regular)	4-5 units	30 min before dinner
HAI correction (BSL 580)	4-5 units SC	Immediately tonight
Lantus (Glargine)	7 units SC	Bedtime (after BSL starts falling)

Lantus Titration (Fasting-Guided, Every 3 Days)

Fasting BSL	Adjust Lantus by
> 180 mg/dL	+2 units
140-180 mg/dL	+1 unit
100-139 mg/dL	No change
< 80 mg/dL	-2 units (hypoglycemia risk)

Key reminders for a 28 kg patient:

Is this a child? If yes, confirm age and whether this is Type 1 or Type 2 - Type 1 in children requires more aggressive basal-bolus management under a pediatric endocrinologist
HAI must be given exactly 30 minutes before meals - if the child refuses to eat after the dose, hypoglycemia can be dangerous
Keep glucagon kit or sugar sachets readily available
Monitor BSL at least 4 times daily until stable
Night BSL of 580 is a medical emergency in a child - hospital admission should be considered

50yr f no ketone present

Good - 50-year-old female, no ketones, weight 28 kg. This is a very low body weight for a 50-year-old woman (severely underweight - likely BMI ~11, normal is 18.5+). No DKA, so this is uncontrolled Type 2 DM (or possibly LADA/Type 1 without ketosis yet). Proceed with SC insulin, but use conservative dosing given low body weight.

Revised Calculation - 50F, 28 kg, No Ketones

Total Daily Insulin (TDI)

For uncontrolled T2DM, severely underweight: use 0.3-0.4 units/kg/day (conservative - low weight = higher hypoglycemia risk)

TDI = 0.3 × 28 = ~8-10 units/day (use 10 for round numbers)

Split 50/50:

Basal (Lantus) = 5 units at night
Bolus (HAI) = 5 units ÷ 3 meals = ~1.5-2 units per meal

Correction Factor

CF = 1500 ÷ 10 = 150 mg/dL per unit

Practically: 1 unit HAI drops BSL by ~150 mg/dL

Target BSL = 140 mg/dL (slightly relaxed target for underweight/frail patient to avoid hypoglycemia)

HAI Doses

Morning (Fasting BSL = 318 mg/dL)

Correction = (318 - 140) ÷ 150 = 178 ÷ 150 = ~1 unit
Mealtime bolus = 2 units
Total morning HAI = 3 units (30 min before breakfast)

Afternoon/Lunch (PP BSL = 400 mg/dL)

This is post-meal reading - give correction at next meal
Correction = (400 - 140) ÷ 150 = 260 ÷ 150 = ~2 units
Mealtime bolus = 2 units
Total lunch/evening HAI = 4 units (30 min before dinner)

Midday lunch dose (no specific reading given)

Mealtime bolus only = 2 units (30 min before lunch)

Night (BSL = 580 mg/dL) - Act Now

Correction = (580 - 140) ÷ 150 = 440 ÷ 150 = ~3 units HAI SC immediately
Recheck BSL after 2 hours
Then give Lantus at bedtime

Lantus Night Dose

Basal = 50% of TDI = 50% of 10 = 5 units SC at bedtime

For this underweight patient, start conservatively at 4-5 units and titrate up.

Important Clinical Notes for This Patient

Concern	Detail
Weight 28 kg at 50F	Severely underweight - investigate cause (malabsorption, TB, malignancy, eating disorder). Nutrition support needed alongside insulin.
No ketones but BSL 580	Likely hyperosmolar tendency - ensure adequate oral hydration (water, ORS)
Hypoglycemia risk	Very high with low body weight - keep sugar/glucose tablets at bedside
HAI timing	Must eat within 30 min of injection - do NOT inject if patient not eating
Monitor	BSL 4 times daily: fasting, pre-lunch, pre-dinner, bedtime
Follow-up	Review in 3 days for Lantus titration; HbA1c, renal function, thyroid workup

Refer to physician/endocrinologist for formal assessment, especially to investigate the cause of severe underweight at this age alongside uncontrolled diabetes.
