🛑ABG Use in

1 🛑. Evaluation of Oxygenation:

Determine arterial oxygen (PaO₂) levels in conditions like hypoxemia or respiratory distress.

Assess response to oxygen therapy or mechanical ventilation.

2.🛑 Assessment of Ventilation:

Monitor arterial carbon dioxide (PaCO₂) levels in respiratory failure, COPD, or hyperventilation syndromes.

🛑3. Acid-Base Imbalance:

Diagnose and monitor metabolic or respiratory acidosis/alkalosis in conditions like diabetic ketoacidosis, renal failure, or sepsis.

🛑4. Monitoring Critically Ill Patients:

Track changes in pH, PaO₂, and PaCO₂ during severe illness, trauma, or after major surgery.

Heparin is having an "in vitro" effect on thyroxine (T4) levels.

IV heparin interferes with the thyroid function tests assay on occasions displacing bound thyroid hormone.

#remember 🛑Tricyclic overdose ➡️ give IV bicarbonate #Not and Note
🛑Management

Check U&Es, looking specifically for hypokalaemia, and ABG looking for acidosis.

Hypokalaemia should be corrected. ECG should be done to assess the QRS interval.

Gastric lavage should only be considered if it is within one hour a potentially fatal overdose.

50 g of charcoal can be given if it is within one hour of ingestion.

50 ml of 8.4% sodium bicarbonate should be given if the pH is less than 7.1, QRS interval is more than 0.16 s, or there are cardiac arrhythmias or hypotension.

Indication for sodium bicarbonate in tricyclic poisoning includes wide QRS complex.

Intravenous sodium bicarbonate is the standard initial therapy for patients who develop cardiotoxicity (usually a QRS > 100ms or a ventricular arrhythmia) as a result of tricyclic antidepressant (TCA) overdose.

Mechanism of Sodium bicarbonate action:

alkalinisation of blood to a pH of 7.45-7.55 uncouples TCA from myocardial sodium channels;

also, additional sodium increases extracellular sodium concentration, thereby improving the gradient across the channel.

Intravenous magnesium sulphate can be used as a second-line agent in refractory arrhythmias.

🛑Klebsiella pneumoniae

Classically occurs in alcoholics (Friedlander's pneumonia) and immunosuppressed individuals

can cause cavitating pneumonia

usually affects the upper lobes

Chest x-ray features may include abscess formation in the middle/upper lobes and empyema.

The mortality approaches 30-50%.

Ceftriaxone for pneumonia prevention in ventilated patients with acute traumatic brain injury
●For patients with moderate-to-severe traumatic brain injury who require mechanical ventilation, we recommend a single dose of ceftriaxone (2 g intravenously) within 12 hours of intubation (Grade 1B).

🛑Treating Patients Who Have Helicobacter pylori Infections

Key Recommendations

Because of the association of chronic H. pylori infection with gastric malignancy, all patients who test positive should be treated.

For a patient with a first infection, the preferred regimen is a 14-day course of a bismuth salt, metronidazole or tinidazole, tetracycline, and a proton-pump inhibitor (PPI). A 10-day course is no longer considered to be adequate, and substitution of doxycycline for tetracycline weakens the regimen. Alternative regimens include a rifabutin-based combination or combinations using a novel potassium-competitive acid blocker (vonoprazan; NEJM JW Gen Med Jun 15 2024 and Clin Gastroenterol Hepatol 2024 May 13; [e-pub]) rather than a PPI.

A treated patient should undergo a test of cure at least 1 month after treatment with a breath test, fecal antigen test, or tissue-based test.

Salvage treatment options for patients with persistent infections include the four-drug preferred regimen above (for those who either did not receive it exactly according to recommendations or did not receive it at all) or clarithromycin- and rifabutin-based alternatives.

No good data yet quantitate the overall costs and benefits of routine susceptibility testing to tailor drug choices. However, clarithromycin and levofloxacin should not be used for either primary or salvage treatment without demonstrated susceptibility, and susceptibility testing also is advised when choice of salvage therapy is unclear.

مش بمجرد تقيس ضغط دم المريض وتشوفهSBP/DBP ≥180/110 mm Hg)  بدون  دليل على وجود target-organ damage تروح تعطيه حقنه لازكس او اي parenteral antihypertensive  او انك تزيد من جرعه دواء الضغط الفموي الذي كان ماشي عليه المريض قبل دخوله المستشفى( يعني مشخص ان لدية ارتفاع ضغط الدم ) لانه ممكن يزيد من adverse outcomes

هناك توصيات قبل اتخذ قرار باعطاء دواء لمعالجة ارتفاع ضغط الدم (Asymptomatic elevated blood pressure
اولا  تأكد بأنه تم قياس ضغط الدم للمريض بشكل صحيح
Accurate BP assessment: Assure that the BP cuff is the a ppropriate size for the patient.

تأكد من عدم وجود اسباب reversible لارتفاع ضغط الدم مثل stress او pain او اضطراب في النوم ..الخ
Identify and manage reversible causes of inpatient elevated BP (e.g., stress, pain, sleep deprivation, withdrawal from alcohol or recreational drugs

ايقاف او إنقاص من جرعه الادوية التي قد تساهم في ارتفاع ضغط الدم مثل المحاليل الوريدية  او مسكنات NSAIDs  او corticosteroids


في حاله قررت أن تبدأ بمعالجه ارتفاع ضغط الدم (Asymptomatic elevated blood pressure فقوم بإعادة ادوية الضغط الفمويه التي كان ماشي عليها المريض قبل دخوله المستشفى وبدون رفع الجرعه ،في حاله كان المريض لم يشخص بارتفاع الضغط الدم المزمن من قبل قد ياجل ذلك حتى زياره المريض أخصائي القلب
 If the patient was not on prior BP medications, the decision whether to start oral BP medications during the hospitalization (vs. deferring this decision to outpatient follow-up) should be individualized.

Recent evidence suggests that asymptomatic patients with elevated blood pressure (BP) in the hospital are at risk for adverse outcomes with use of parenteral antihypertensive agents or up-titration of oral agents during the inpatient stay. 


Key Recommendations


🛑Asymptomatic elevated inpatient BP

Accurate BP assessment: Assure that the BP cuff is the appropriate size for the patient.

Identify and manage reversible causes of inpatient elevated BP (e.g., stress, pain, sleep deprivation, withdrawal from alcohol or recreational drugs).

Stop, limit, or reconsider medications that might contribute to elevated BP (e.g., intravenous fluids, nonsteroidal anti-inflammatory drugs, corticosteroids, stimulant medications).

Avoid treatment of asymptomatic elevated inpatient BP (including asymptomatic markedly elevated BP, i.e., SBP/DBP ≥180/110 mm Hg) in most situations.

If choosing to treat markedly elevated inpatient BP without evidence of target-organ damage, start by resuming the patient's home oral BP medications. If the patient was not on prior BP medications, the decision whether to start oral BP medications during the hospitalization (vs. deferring this decision to outpatient follow-up) should be individualized


Hypertensive emergency

Defined as markedly elevated BP (systolic/diastolic, ≥180/110 mm Hg) with evidence of new or worsening target-organ damage. Target-organ systems include brain (e.g., stroke, cerebral hemorrhage, hypertensive encephalopathy or posterior reversible encephalopathy syndrome [PRES]), arteries (e.g., aortic dissection, preeclampsia, eclampsia, HELLP [hemolysis, elevated liver enzymes, low platelets] syndrome), retina (e.g., acute hypertensive retinopathy), kidneys (e.g., acute kidney injury, thrombotic microangiopathy), and heart (e.g., acute coronary syndrome, acute heart failure, pulmonary edema) — denoted by the mnemonic BARKH

🛑Vitamin D  supplements

When supplementation is given, low daily doses are recommended (rather than high doses given at intervals such as weekly or monthly), because evidence suggests some adverse effects with intermittent high dosing.
