APRV Lung Demonstration | Resus Review

Unlike spontaneous breathing or conventional ventilation, the time spent at maximal inflation is typically much longer than time deflated. Time low is minimized to prevent collapse of alveoli and barotrauma. The video below shows shows treated pig lungs being ventilated with typical APRV settings.

lump-in-my-throat

A 19-year-old-male with no known past medical history, presents in progressive respiratory distress shortly after undergoing a tooth extraction about 6 hours prior to presentation. Symptoms began initially as “a lump in his throat” and difficulty swallowing, but eventually progressed to mild dyspnea after 1-2 hours. Denies FB or allergies. On arrival he appears anxious and is breathing at 18 breaths per minute with an O2 saturation of 100%. There is no stridor at presentation. There is no intra-oral, facial, or obvious neck swelling. There is no skin involvement or abdominal pain, nausea, vomiting or diarrhea. You suspect allergic reaction and give IM epi, IV steroids, benadryl and pepcid. ENT is consulted for scope.

SGEM#62: Take My (Shortness of) Breath Away – Nebulized Furosemide for COPD

Case Scenario: 73yo man presents to the emergency department with an exacerbation of his COPD. He quit smoking two days ago when his breathing got worse. He has a history of hypertension but no history of congestive heart failure. He has been taking all his medication and puffers as prescribed. Vital signs are BP165/85, HR 95, Temp 37.2C, RR 22 and O2 Sat 92% on room air.

Preoperative skin antiseptic for prevention of surgical wound infections after clean surgery | Cochrane

Patients' skin at the operation site is routinely cleansed with antiseptic solutions in the operating theatre before surgical incisions are made. This skin cleansing with an antiseptic aims to reduce the microorganisms present on the skin and therefore reduce the risk that the surgical wound will become infected. It is not known whether one antiseptic treatment is better than any other(s) at preventing infection, so our team examined the evidence for antiseptic skin preparation prior to clean surgery (i.e. surgery that does not involve the breathing system, gut, genital or urinary tract or any part of the body with an existing infection) to see if there are differences between preoperative antiseptic treatments. Unfortunately there is very little good quality research around skin cleansing before surgery and we cannot say whether one antiseptic is better than another at preventing wound infections. More research is required to show whether one antiseptic is better than the others at preventing wound infection after clean surgery.

Critical Care

Intrinsic positive end-expiratory pressure (PEEPi) is a “threshold” load that must be overcome to trigger conventional pneumatically-controlled pressure support (PSP) in chronic obstructive pulmonary disease (COPD). Application of extrinsic PEEP (PEEPe) reduces trigger delays and mechanical inspiratory efforts. Using the diaphragm electrical activity (EAdi), neurally controlled pressure support (PSN) could hypothetically eliminate asynchrony and reduce mechanical inspiratory effort, hence substituting the need for PEEPe. The primary objective of this study was to show that PSN can reduce the need for PEEPe to improve patient-ventilator interaction and to reduce both the “pre-trigger” and “total inspiratory” neural and mechanical efforts in COPD patients with PEEPi. A secondary objective was to evaluate the impact of applying PSN on breathing pattern.

Strategies used for the withdrawal of humidified high flow nasal cannulae (HHFNC) in preterm infants | Cochrane

Background: Humidified high flow nasal cannula (HHFNC) is a form of respiratory support used in the treatment of preterm infants. Potential risks of HHFNC include damage to the nose and leaking of air from the lungs. Infants on HHFNC require more nursing care and the use of extra equipment (when compared to not being on any support). However, potential complications of removing HHFNC from babies too early include increased episodes of forgetting to breathe, increased oxygen needs, increased effort of breathing, the need to restart HHFNC, and the need for a breathing tube with mechanical ventilation. Any of these complications can be seen as a "failure" and are potentially distressing to staff and family. The best way to withdraw HHFNC once it has been started is unknown. Options include simply stopping, weaning the flow, increasing the time off HHFNC each day, or combinations of both.

Continuous distending pressure for respiratory distress in preterm infants | Cochrane

Review question: In spontaneously breathing preterm infants with respiratory failure, does continuous distending pressure (CDP) of the lung reduce the need for assisted ventilation and other associated complications of prematurity?

Effects of opioid, hypnotic and sedating medications on obstructive sleep apnoea (OSA) in adults with known OSA | Cochrane

Obstructive sleep apnoea (OSA) is a common sleep disorder characterised by intermittent apnoeas (pauses in breathing) leading to dips in oxygen levels in the blood during sleep. Many people with known or unknown (undiagnosed) OSA receive hypnotics, sedatives and opiate/opioid drugs to treat other conditions including pain, anxiety and difficulty sleeping. Opiates/opioids are commonly prescribed to treat pain after major surgery. These drugs might make sleep apnoea worse - increasing the frequency and duration of apnoeas.

Fresh frozen plasma for patients undergoing surgery on the heart or blood vessels | Cochrane

Fresh frozen plasma is obtained from whole blood from blood donors. It contains a number of factors that help blood to clot. The risk of bleeding in open heart surgery or surgery on the main blood vessels in the body is high. Fresh frozen plasma is sometimes administered to these patients to reduce bleeding. It can be administered prophylactically (to prevent bleeding) or therapeutically (to treat bleeding). However, there are risks of side effects from fresh frozen plasma, such as severe allergic reactions or breathing problems.

Can taking inhaled corticosteroids when needed for symptoms help people with mild asthma from becoming more unwell? | Cochrane

Daily inhaled corticosteroids (ICS) are the mainstay of medications prescribed for people with asthma who have ongoing difficulty with their breathing. However, for those with a milder form of the condition, it is hard to predict when their asthma will get worse and so many people do not use their inhaler regularly. In this review, we compared the use of ICS used intermittently at the start of an asthma episode with placebo treatment in children and adults with mild asthma (two trials representing 385 participants) and in preschool children deemed to be at risk of developing asthma symptoms in the future (four trials representing 490 participants).

Does hyperbaric oxygen therapy improve outcome after heart attack? | Cochrane

Acute heart attacks and severe angina (heart pain) are usually due to blockages in the arteries supplying the heart (coronary arteries). These problems are collectively referred to as 'acute coronary syndrome' (ACS). ACS is very common and may lead to severe complications including death. Hyperbaric oxygen therapy (HBOT) involves people breathing pure oxygen at high pressures in a specially designed chamber. It is sometimes used as a treatment to increase the supply of oxygen to the damaged heart in an attempt to reduce the area of the heart that is at risk of dying.

"Dry drowning" the summer medical oxymoron

Undoubtedly you will see a child with a “near drowning” if you work in the ED during the summer. Most children are fine, even those that received some back blows, mouth to mouth or some semblance of bystander rescue maneuvers. Asymptomatic children (no respiratory symptoms) can be safely discharged home. Those that are having difficulty breathing or other symptoms should receive appropriate respiratory support and be followed closely clinically and with chest x-rays when the situation changes. All symptomatic children should be admitted to the hospital.

Surgical versus nonsurgical interventions for flail chest (ribs with more than one fracture) | Cochrane

Flail chest is a medical term describing multiple rib fractures, when ribs are broken or dislocated in more than one place and are no longer completely connected to the other rib bones. When a person injured in this way breathes, the broken segment may move in a different way compared to the rest of the chest wall. Flail chest can cause a person to have difficulty breathing, in which case they may be given mechanical ventilation (machine-assisted breathing). Surgery is sometimes performed in order to reconnect the broken ribs.
