PATIENT’ S CMR

PATIENT PARTICULARS

• NAME: MISS ABC• BED/WARD: C1/17• AGE: 70• DIAGNOSIS : UROSEPSIS• DATE OF ADMISSION: 12/7/2010• DATE OF DISCHARGE : 8/8/2010

Brief overview : UROSEPSIS Definition: sepsis (septicaemia syndrome) caused by urinary 

tract infection Urosepsis in adults comprises approximately 25% of all sepsis

cases and in most cases is due to complicated urinary tract infections (UTIs)

Classic presentation: fever, chills, hypotension in some patient Patients who are more likely to develop urosepsis include:

infant,elderly patients, diabetics, immunosuppressed patients (such as transplant recipients), patients receiving cancer chemotherapy or corticosteroids and patients with acquired immunodeficiency syndrome(HIV)

Clinical diagnostic criteria of sepsis

Associated with Systemic Inflammatory Response Syndrome(SIRS):

i) Temperature > 38 C or < 36 Cii) Heart rate > 90 beats per minuteiii)Respiratory rate > 20 breaths or PaC02 < 32

mmHgiv) White blood cells > 12 x 10^9/L

For therapeutic purposes, the diagnostic criteria of sepsis should identify patients at an early stage of the syndrome, prompting urologists and intensive care specialists to search for and treat infection, initiate appropriate therapy, and monitor for organ failure and other complications

In the case of urosepsis the clinical evidence of UTI is based on symptoms, physical examination, sonographic and radiological features, and laboratory data, such as bacteriuria and leucocyturia.

Pathophysiology of urosepsis

• Micro-organisms reach the urinary tract by way of the ascending, haematogenous or lymphatic routes. For urosepsis to be established, from the urinary tract the pathogens have to reach the bloodstream. The risk of bacteraemia is increased in severe urogenital infections such as pyelonephritis and acute bacterial prostatitis, and is facilitated by obstruction.systemic inflammatory response syndrome (SIRS) is then triggered

General Management of Urosepsis

• Effective treatment eliminates the infectious sources, and improves organ perfusion. Treatment of urosepsis comprises four basic strategies:

i) supportive therapy (fluid replacement therapy for stabilisation and maintaining blood pressure, manage fluid and electrolyte balance)

ii) antimicrobial therapy (initiate with broad spectrum antibiotic within in the first hour)

iii) control or manage of the complicating factor, &iv) specific sepsis therapy(eg.corticosteroid, insulin, etc)

All four strategies need to be started as early as possible.

• Appropriate and early diagnosis of sepsis is important to enable commencement of treatment without delay-if left untreated it can cause severe sepsis & septic shock

• According to Kumar et al.’s data [7],we have 1 h to administer broad-spectrum antibiotics. We have 6 h to stabilise haemodynamics according to early goal-directed therapy. We have 24 h to apply adjunctive therapy

Severe Sepsis association with organ dysfunction, hypoperfusion or hypotension- may include but are not limited to lactic acidosis, oliguria or an acute alteration of mental statusSeptic shock- Sepsis with hypotension despite adequate fluid resuscitation

DRUG THERAPY GIVEN(based on CMR)

• HYDROCHLOROTHIAZIDE• NIFEDIPINE • AMLODIPINE• PCM• LOVASTATION• TAZOCIN• OMEPRAZOLE• UNASYN• RANITIDINE

• MAXOLON(• COLCHICINE• TICLIDOPINE• PREDNISOLONE• METOPROLOL• MIST KCL• NEUPOGEN• ALBUMIN• SYPLACTULOSE

Hydrochlorothiazide( HCTZ)

• INDICATION: Management of mild to moderate hypertension, treatment of edema in congestive heart failure, corticosteroid therapy and nephrotic syndrome

• ACTION: Inhibits sodium reabsorption in the distal tubules causing increased excretion of sodium(&chloride) and water

• Half life: 5.6-14.8 hour• Onset of action ~ 2hours (duration 6-12hours)

DOSAGE

IN ADULTEDEMA(25-100mg/day , max 200mg/day)HTN(12.5-50mg/day)

In elderly patient : 12.5-25 mg once daily(from the prescription dose given is 25mg po od)

Warning /Precaution• Should avoid in renal disease(ineffective)• Electrolyte disturbance(hypokalemia, hyponatremia etc) can

occur• May precipitate gout(cause hyperuricemia)• Use in caution with diabetes patient(may alter glucose control)• Use in caution in patient with high cholesterol• ADR: 1-10% :orthostatic hypotension, photosensitivity,

hypokalemia, hyponatremia, anorexia, epigastric distress• Contraindications Hypersensitivity to thiazides, related diuretics,

or sulfonamide-derived drugs; anuria; renal decompensation• Hepatic impairment: Minor alterations of fluid and electrolyte

balance may precipitate hepatic coma; use drug with caution

DRP detected: Drug-drug interactions

1) Hydrochlorothiazide + prednisoloneLevels/effect of hydrochlorothiazide may be increased by corticosteroid (prednisolone)

still can be used together 2) Hydrochlorothiazide + amlodipine

The antihypertensive effect of amlodipine and thiazide diuretics may be additive. Management consists of monitoring blood pressure during coadministration, especially during the first 1 to 3 weeks of therapy.

PATIENT CARE CONSIDERATIONS

Administration/Storage• If drug is administered as single dose, give in

morning. • Administer drug with food or milk to minimize

GI irritation. • Store tablets in tightly closed container at

room temperature

Assessment/Interventions• Monitor patient's BP with patient lying down and standing. • Monitor serum potassium, calcium, magnesium, sodium, ABGs, uric acid. • Monitor renal ( BUN, creatinine) and liver (ALT, AST) function tests. • Monitor blood glucose levels in diabetic patients. • Observe closely for anaphylaxis (shortness of breath, rash, edema) after

first dose. • Report muscle weakness, cramps, nausea, blurred vision, or dizziness to

health care provider• Advise patient to limit sodium intake for optimal drug effect• Caution patient to avoid sudden position changes to prevent orthostatic

hypotension• Advise patient that drug may cause drowsiness and to use caution while

driving or performing other tasks requiring mental alertness
