Q

Beck’s triad is for what and components

A

Pulsus paradoxus, also known as paradoxical pulse, is a condition where a person’s systolic blood pressure, stroke volume, and pulse wave amplitude drop abnormally during inhalation. It’s a sign of heart or lung disease and is the opposite of what would normally happen, as blood pressure usually increases when someone inhales.

For cardiac tamponade
Hypotension
Raised JVP
Muffled heart sound
And
There will be a pulsus paradoxus

Q

When to suspect fat embolism and
Management

A

After long bone fractures
Liposuction
Mx
Fat embolism syndrome (FES) is generally treated with supportive care in the hospital, often in the intensive care unit. Treatment focuses on maintaining intravascular volume and ensuring good arterial oxygenation. Some treatments include:
Oxygen
One of the fastest and easiest treatments for respiratory problems. You may be given oxygen or need help breathing with mechanical ventilation.
Intravenous fluids
Helps remove damaging free fatty acids from the body. Human albumin is recommended to restore blood volume and bind to fatty acids to reduce lung injuries.
Drugs
Your doctor may prescribe steroids or the blood thinner heparin, but these drugs have not been proven to be highly effective.
Surgical management
This includes early stabilization of long-bone fractures, rigid fixation within 24 hours, and appropriate surgical technique.

Q

Massive pulmonary embolism Mx
Vs
Small embolism

A

British thoracic society guideline
Massive
3mg bolus of alteplase
Heparin
Thrombus fragmentation
IVC filter insertion
Small
Heparin if high probability of embolism before imagine like unfractionated heparin in massive pulmonary embolism where rapid reversal is needed. If not then LMWH cause it has the same efficacy and is easier to administer upto reaching INR 2-3
Oral anticoagulant should be used only after confirmation of embolism upto 4-6 weeks with temporary risk factors,3 months for idiopathic,6 months for any other reason

*Rebound release of catecholamines may cause hypertension, tachycardia, and ventricular arrhythmias. Pulmonary edema has also been observed after naloxone administration. Small doses of naloxone can precipitate a withdrawal syndrome in subjects that are opioid-dependent.

39
Q

Compartment syndrome

A

Compartment syndrome can occur in any muscle, but it’s most common in the forearms and lower legs. Symptoms can be difficult to detect, and can become severe within a few hours of an acute injury. Some early signs of compartment syndrome include:
Pain
Pain that’s more severe than expected from the injury, and that doesn’t go away after taking pain medication or raising the affected area. The pain may feel like a deep ache or burning sensation, and it can get worse when you move the affected body part.
Swelling
The muscle may swell or bulge, or you may have difficulty moving the affected body part.
Other sensations
You may experience numbness, tingling, or a burning feeling under your skin (paresthesia). The skin may also appear pale.
Other signs of compartment syndrome include: tightness, weakness, and pins and needles.
Numbness and paralysis are later signs of compartment syndrome, and usually indicate permanent tissue injury.
Compartment syndrome can be caused by fractures, severe contusions, crush injuries, or reperfusion injury after vascular injury and repair.
