A doctor's examination and plain chest X-ray may be all that is needed to diagnose atelectasis. “Wind, water, wound, walking, wonder drugs” are described as the “Ws” of post-operative fevers (atelectasis, UTI, wound infection, DVTs, and drug fevers, respectively). Estimates from different surgical procedures reveal that fever occurs early in the postoperative period anywhere from 20% to 90% of patients. What’s so bad about having a fever? Postoperative fever is very common. These fevers are probably the result of surgical trauma. There is a characteristic timeframe after surgery when many of these complications tend to develop (postoperative days or POD). Ultr… Atelectasis has a high prevalence in the postoperative period and therefore its coexistence with fever is not surprising. Atelectasis is considered to be the most common cause of early postoperative fever (EPF) but the existing evidence is contradictory. The exact incidence of postoperative fever is not known, but the numbers are high. Although atelectasis is considered to be the most common cause of early postoperative fever, the existing evidence is contradictory. Estimates from different surgical procedures reveal that fever occurs early in the postoperative period anywhere from 20% to 90% of patients. However, other tests may be done to confirm the diagnosis or determine the type or severity of atelectasis. Textbooks have long listed the common causes of postoperative fever using the mnemonic of “W”s in the order of: Wind (atelectasis) Water (urinary tract infection) Wound (wound infection) Walking (venous thromboembolism) Wonder drug (drug fever) Fever … Pyrexia (fever) refers to a raised body temperature, typically greater than 37.5c.It is common in surgical patients, either due to the underlying disease process or as a post-operative complication. Atelectasis can be a minor complication, but it can become a very serious complication when the patient has other serious issues after surgery. The purpose of this thesis is to determine whether atelectasis alone Lung Atelectasis is another cause of post-operative fever. An experimental method for production of … It helps determine the severity of atelectasis. Symptoms vary depending on the cause and extent of atelectasis. If the early post op fever is not ascribed to atelectasis think of how many useless workups for pnuemonia will be undertaken after reviewing post op cxr read as pna vs. atelectasis. Postoperative fever is very common. They include: 1. Even if the catheter comes out right away, it is still possible that bacteria was introduced into the urethra during insertion. Water (UTI) Water or UTI is the most common of post-op infection in the time window of 48-72 hours. Answer. Beside this, does atelectasis cause fever after surgery putting a damper on dogma? Another common cause of post-op fever is a urinary tract infection due to the catheter used during surgery. Even if the catheter comes out right away, it is still possible that bacteria was introduced into the urethra during insertion. differential for postoperative respiratory distress includes atelectasis, pneumonia, aspiration, pulmonary edema, acute respiratory distress syndrome (ARDS), pulmonary embolism, fat embolism, and narcotic overdose. Majority of the time, a fever is indicative of an infection of either viral or bacterial origin. Symptoms of Atelectasis : Breathing difficulty, Chest pain, Cough, Fever, low-grade, usually after surgery. Often, post-operative “atelectasis” is the result of supine (as opposed to upright) films. See the above section on Postoperative Fever for descriptions. Atelectasis was associated with neither the presence nor the severity of fever. [19] Atelectasis AND pneumonia. 4,7,26 In addition, fevers after total joint arthroplasty do not seem to be predictive of wound infection or urinary tract infection. This physiologic adaptation to surgery often is evident in the first 48 hours after surgery and is responsible for most postoperative fevers. a complete or partial collapse of the entire lung or area (lobe) of the lung. Vermeulen and colleagues15 reviewed the records of 284 general surgery patients, who had 2282 temperatures taken. The exact incidence of postoperative fever is not known, but the numbers are high. CT scan.Since a CT is a more sensitive technique than an X-ray, it may sometimes help better detect the cause and type of atelectasis. However, current evidence suggests that atelectasis correlates poorly with postoperative fever, and that the previously ascribed relationship is coincidental rather than causative. Dr. O’Glasser recommends framing the conversation in terms of humility, and understanding that your … The notion is entrenched in surgical textbooks and frequently discussed on morning rounds in the hospital. Most fevers that develop within the first 48 hours after surgery are benign and self-limiting. Postoperative fever should be evaluated with a focused approach rather than in "shotgun" fashion. Any fever that develops in the hours or days after a surgical procedure is considered a postoperative fever. Putting a Damper on Dogma. A patient with a postoperative fever in the first three days may or may not have atelectasis, but the atelectasis is NOT the cause of the fever. In children undergoing cardiac surgery with cardiopulmonary bypass, fever in the postoperative period should not be att … Atelectasis and pneumonia frequently occur in the post-operative period. Wind (atelectasis) Post-op fever that occurred in the first 24-48 hours is caused by wind. Certain drugs also tend to increase temperature. Some call this "physiologic" fever. Fever is usually attenuated by general anesthesia. The post-operative atelectasis may occur within 48 hours of surgery. This can be prevented by stopping the smoking 6 to 8 weeks prior to surgery and the patient is advised with certain breathing exercises. Postoperative fever and atelectasis are both common after pediatric cardiac surgery. phlebitis. After induction of anesthesia, atelectasis increases from 1 to 11% of total lung volume. Postoperative fever is commonly attributed to atelectasis when no other source is found, but evidence for that presumption is lacking. Oximetry.This simple test uses a small device placed on one of your fingers to measure your blood-oxygen level. For example, serotonergic drugs, antidopaminergic drugs (cause neuroleptic malignant syndrome), Sulfa antibiotics, Cocaine, Methamphetamine, Progesterone, Chemotherapeutics, anti-histamines, cimetidine among the many others may cause fever. Atelectasis does not cause post-op fever! End-expiratory lung volume is … Pulmonary atelectasis, a common postoperative complication, is associated with high fever, tachycardia, and a rapid respiratory rate. Whilst infection is regularly the suspected cause, other conditions must be considered when approaching the surgical patient with pyrexia (Fig. The stimuli for these changes and the mechanisms whereby they are effected are the topics of this paper. However, current theories suggest that airway collapse is due to a combinationof airway compression (Fig. Engoren17 showed that the incidence of atelectasis increased as the incidence of fever decreased with each successive postoperative day. 1), alveolar gas resorption intra-operatively, and impairment of surfactant production. Atelectasis is diagnosed by clinical exam, close monitoring of a post-operative clinical course, and x-ray. 11–13,27 Work outside the field of orthopaedics has shown that the presence of atelectasis does not correlate with fever. A 2011 systematic analysis of 8 published studies found that all but 1 study failed to find a significant association between postop fever and atelectasis. Treatment Strategies to Consider Early in Postoperative Hepatic Failure: jaundice ... Common cause of fever after 72 hrs post-op. Atelectasis, in and of itself, has not been shown to cause fever. However, atelectasis may give rise to bacterial infection, which does cause fever. A patient with a postoperative fever in the first three days may or may not have atelectasis, but the atelectasis is NOT the cause of the fever. More likely, the patient has a benign fever resulting from cytokine release related to the surgery. Fever and atelectasis are common after surgery, and in the absence of infectious causative mechanisms, atelectasis is commonly thought to be a cause of fever. Atelectasis is considered to be the most common cause of early postoperative fever (EPF) but the existing evidence is contradictory. 2. More likely, the patient has a benign fever resulting from cytokine release related to the surgery. Postoperative complications may either be general or specific to the type of surgery undertaken and should be managed with the patient's history in mind. 3. We sought to determine if atelectasis is associated with EPF by analyzing the relevant published evidence. In the case of a viral infection, it might not even be necessary to see a doctor. The atelectasis is typically basilar and segmental in distribution. ... Another common cause of post-op fever is a urinary tract infection due to the catheter used during surgery. Prevention of postoperative complications. Fever and atelectasis are common after surgery, and in the absence of infectious causative mechanisms, atelectasis is commonly thought to be a cause of fever. “Atelectasis” There is no correlation between atelectasis and fever [Heart Lung 17: 166, 1988]. Look for other causes of early postoperative inflammatory response. We sought to determine if atelectasis is associated with EPF by analyzing the relevant published evidence. A small area is probably asymptomatic (absence of symptoms). During our medical school and residency years, many of us learned the “Rule of W” as a helpful mnemonic for causes of postoperative fever: Wind (pulmonary causes, including atelectasis), Water (urinary tract infection), Wound (infection), Walking (deep venous thrombosis), and Wonder Drugs (drug fever). Although it was previously believed that atelectasis by itself can cause fever, no association between atelectasis and fever has been demonstrated. Common general postoperative complications include postoperative fever, atelectasis, wound infection, embolism and deep vein thrombosis (DVT). Most early postoperative fever is caused by the inflammatory stimulus of tissue damage and exposure to foreign materials that occurs during surgery and resolves spontaneously over a few days. An individual who is kept on a ventilator after surgery is likely already very ill and atelectasis can be an unwanted complication as it can lead to more serious lung problems than those that already exist. Prevention of Atelectasis. Encourage movement and deep breathing in anyone who is bedridden for long periods. A number of current surgical texts state that fever appearing shortly after operation is often due to atelectasis, although few provide an explanation of the pathogenesis of the fever.

The classic list consists of five W's – Wind, Water, Wound, Walking, and Wonder Drugs, but two other causes should also be considered – Wing/Waterway and (W)abscess. ... but newer studies have shown no association between the degree of atelectasis and postoperative fever. This study assessed the relation between fever and atelectasis in 100 patients who had chest x-rays right after cardiac surgery and on the first and second postoperative days. The pathophysiology of atelectasis is not fully understood. Post-operative care can be collaborative. Yikes! However, it is critical that physicians who provide postoperative care be able to recognize the minority of … Illness caused by a virus is self-limiting, so all you really need to do is ride it out until it subsides. Postoperative atelectasis: one of the most common post-operative complications (especially after chest or abdominal surgery); often occurs within 72 hours of surgery Rounded atelectasis : folding of the atelectatic lung tissue (with fibrous bands and … In our study, there was no significant association between postoperative fever and atelectasis.
