If yоu cultured а bаcterium оn EMB mediа and they did nоt grow,
Yоu аre оbserving аn аppendectоmy. The patient, Kevin, is a 20-year-old male who was healthy until two days ago when he began having severe abdominal pain, fever, and vomiting resulting in a diagnosis of appendicitis. The case has been in progress for about 20 minutes when you notice Kevin's heart rate jump up to 120bpm, setting off the ECG alarm on the monitor. Kevin's temperature has gradually begun to rise and is now 101.8°F (38.8°C). His exhaled carbon dioxide levels have also begun to rise. "We need to get the malignant hyperthermia cart right away!" says the doctor. Kevin is now two days post-operative and is recovering in the Surgical Intensive Care Unit. You recall all of the activities that occurred to save his life by treating his malignant hyperthermia. You researched this condition and discovered that it is an inherited disease. While under general anesthesia, the affected person will experience severe muscle contractions and a rapid rise in body temperature that can become life-threatening. Malignant hyperthermia is treated with dantrolene, which blocks receptors that release Ca2+ from the sarcoplasmic reticulum, thus preventing muscle contraction. Questions: 1) Heat production comes from (among other things) ATP hydrolysis. What are the different steps during muscle contraction that require ATP? 2) The doctor looked at the patient's temperature, CO2 levels, and heart rate before diagnosing malignant hyperthermia. Explain how those three measurements were connected to the diagnosis. 3) While under anesthesia, a patient undergoing malignant hyperthermia is experiencing severe muscle contractions. Would the patient be aware of this? Explain your reasoning. 4) Dantrolene blocks Ca2+ channels on the sarcoplasmic reticulum and prevents Ca2+ release. How does this block muscle contraction?
