Experience with Heat Stroke During an Event

A 25-year-old individual weighing 75 kilograms (approximately 165 pounds) had no existing medical prescriptions. This person participated in an event held in a sweltering environment with temperatures soaring to 34 degrees Celsius (93.2 degrees Fahrenheit). During the event, they began to notice alarming signs associated with heat stroke, characterized by excessively warm skin, an absence of sweating, a severe headache, and overwhelming fatigue. Emergency first aid was summoned, revealing a blood pressure of 190/105 and a heart rate of 110. The person was subsequently transported to a medical professional where wet towels and later ice packs were applied to assist in cooling down. Tests indicated that blood sugar and oxygen levels were within normal ranges. Although advised to hydrate gradually with water, the individual quickly experienced nausea and vomited. To combat the vomiting, a Primperan tablet (which contains Metoclopramide) was administered. Following further guidance to sip water slowly, this approach remained effective for roughly half an hour before the vomiting episode recurred. An intravenous infusion of Normal Saline 0.9% at 500 cc was then provided, allowing the individual to maintain hydration without further complications. After the treatment, medical staff recommended that an ambulance might be necessary due to the elevated blood pressure. However, this was later altered, and the individual was allowed to leave with warnings about specific symptoms to monitor. Approximately four hours post-initial treatment, blood pressure readings had improved to 150/91. ### Inquiries 1. One week later, the individual feels completely recovered. Is there a necessity for a follow-up appointment with a primary care physician? 2. Given that heat stroke typically results in lower blood pressure, why was the blood pressure reading so high in this case?

1. Follow-Up Necessity: Given that the individual feels completely recovered one week later, a follow-up appointment with a primary care physician is not strictly necessary. However, it is prudent to schedule one if any new symptoms arise or if there are lingering concerns about recovery, particularly related to blood pressure management or heart rate normalization.

2. Understanding High Blood Pressure in Heat Stroke: It's true that heat stroke typically leads to a drop in blood pressure due to dehydration and cardiovascular stress. However, in some cases, as seen here, high blood pressure can occur, particularly if the individual experienced significant stress, was dehydrated, or had an increase in heart rate due to the heat. The body's response can vary based on multiple factors, including hormonal responses to stress and fluid balance, which can lead to transient spikes in blood pressure even during heat-related illnesses.

Next Steps:

1. Monitor Your Health: Continue to monitor blood pressure and any symptoms of fatigue, headache, or irregular heartbeats for at least a few more days. If any concerning symptoms develop, seek further evaluation.

2. Hydration and Rest: Ensure adequate hydration with water or electrolytes, particularly in warmer weather, and rest regularly to allow your body to recover.

3. Education on Heat Exposure: Educate yourself on recognizing early signs of heat-related illnesses and how to manage heat exposure, especially during physical activities in hot conditions.

4. Lifestyle Adjustments: Consider gradual acclimatization to heat when participating in outdoor activities, ensuring to hydrate before, during, and after strenuous events.

If any new concerns arise, such as persistent fatigue, headaches, or high blood pressure readings, don't hesitate to consult a healthcare provider for in-depth evaluation and support.
