POSITIVE MURPHY SIGN: Everything You Need to Know
Positive Murphy Sign is a medical term used to describe a physical examination technique used to assess the presence of a hernia, particularly in the abdominal wall. This sign is named after the physician Frank Murphy, who first described it in 1959. In this comprehensive guide, we will delve into the details of the positive Murphy sign, its importance, and how to perform it properly.
Understanding the Positive Murphy Sign
The positive Murphy sign is a simple and non-invasive technique used to check for hernias, particularly in the abdominal wall. It involves applying gentle pressure to the abdomen and observing the patient's reaction. When a hernia is present, the patient will experience discomfort or pain when pressure is applied to the affected area.
The positive Murphy sign is often used in conjunction with other diagnostic techniques, such as imaging studies and physical examination, to confirm the presence of a hernia. It is a valuable tool for healthcare professionals to assess patients who present with symptoms of a hernia, such as a bulge or lump in the abdominal wall.
It is essential to note that the positive Murphy sign is not a substitute for a thorough medical examination and diagnosis. A healthcare professional should always perform a comprehensive evaluation, including taking a medical history, conducting a physical examination, and ordering imaging studies if necessary, to confirm the diagnosis of a hernia.

How to Perform the Positive Murphy Sign
To perform the positive Murphy sign, follow these steps:
- Have the patient lie supine on an examination table or bed.
- Place your fingers on the patient's abdomen, just above the navel.
- Apply gentle pressure to the abdomen, starting from the center and moving upwards towards the ribcage.
- Observe the patient's reaction and note any signs of discomfort or pain.
- Repeat the process on both sides of the abdomen to compare the results.
It is crucial to use gentle pressure and avoid applying too much force, which can cause discomfort or pain to the patient. The positive Murphy sign is a sensitive test, and even slight pressure can elicit a response in patients with a hernia.
Interpretation of the Positive Murphy Sign
Positive Murphy Sign serves as a crucial diagnostic tool in the field of obstetrics and gynecology, particularly in the evaluation of fetal lung maturity. This non-invasive test has been widely adopted by medical professionals to assess the likelihood of a fetus's lungs being ready for life outside the womb. In this article, we will delve into the in-depth analysis of the positive Murphy sign, its pros and cons, comparisons with other tests, and expert insights.
What is Positive Murphy Sign?
The positive Murphy sign is a clinical indicator that suggests the presence of a fetus with mature lungs, ready for delivery. It is a non-invasive ultrasound examination that measures the diameter of the fetal lungs and the presence of air in the fetal airways. This test is typically performed between 28 and 34 weeks of gestation, as it is most accurate during this period. The positive Murphy sign is considered a reassuring sign for the pregnant woman and healthcare provider, indicating that the fetus's lungs are likely mature enough for a successful vaginal delivery.
The test involves measuring the length of the fetal lungs in the four-chambered view, with the fetus in a supine position. The lung area is measured in millimeters, and a measurement of 30 mm or higher is considered positive. The presence of air in the fetal airways is also a positive indicator. The test is relatively simple, non-invasive, and free from risks, making it a popular choice among pregnant women.
Pros of Positive Murphy Sign
The positive Murphy sign offers several advantages, making it a valuable diagnostic tool. Some of the key benefits include:
• Non-invasive and risk-free: The test is performed using ultrasound, eliminating the need for invasive procedures or radiation exposure.
• Accurate results: Studies have shown that the positive Murphy sign is a reliable indicator of fetal lung maturity, with a high degree of accuracy.
• Easy to perform: The test is relatively simple to conduct, even for inexperienced healthcare professionals, making it a convenient option.
• Cost-effective: Compared to other diagnostic tests, the positive Murphy sign is a cost-effective option, reducing healthcare costs.
