RESUMO
OBJECTIVE: This study aimed to assess the physiological changes and clinical outcomes in patients with chronic obstructive pulmonary disease (COPD) undergoing laparoscopic cholecystectomy. METHODS: This prospective cohort study included 50 patients of the American Society of Anesthesiology (ASA) physical status I and II with mild to moderate COPD (Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage I-II) scheduled for laparoscopic cholecystectomy. We monitored heart rate, mean arterial pressure, end-tidal carbon dioxide (EtCO2), arterial carbon dioxide (PaCO2), and bicarbonate (HCO3) levels at baseline, 30 minutes after induction or 15 minutes post-insufflation, 15 minutes post-deflation, and 60 minutes post-operative. Perioperative complications and post-operative recovery characteristics were also observed. Descriptive statistics were used to summarise the demographic and clinical characteristics of the patients. The correlation between HCO3 and EtCO2 was plotted on a scatterplot, and Pearson's correlation 'r' was calculated. The changes in physiological parameters over time were analysed using a paired t-test. A p-value of less than 0.05 is considered statistically significant. RESULTS: We observed a statistically significant but transient increase in heart rate, mean arterial pressure, and EtCO2 at 30 minutes after induction or 15 minutes post-insufflation, which returned to baseline levels within 15 minutes of deflation. Similarly, arterial CO2 and bicarbonate levels were also significantly increased at 15 minutes post-insufflation, yet remained within the normal physiological range. The study reported no serious perioperative complications, and all patients had an uneventful recovery. CONCLUSION: While patients with mild to moderate COPD can experience transient physiological changes during laparoscopic cholecystectomy, these changes are generally well-tolerated and not associated with adverse clinical outcomes. Therefore, laparoscopic cholecystectomy can be considered a safe procedure in these patients. Future research should focus on the implications and safety of this procedure in patients with severe COPD.
RESUMO
Introduction and importance: Thyrotoxic periodic paralysis (TPP) is a rare and often misdiagnosed, hypokalemic periodic paralysis with features of mainly recurrent acute limb weakness with good treatment outcome if diagnosed early. Case presentation: We here report a case of a 25-year-old male with a history of recurrent bilateral upper and lower limbs weakness resolved by potassium infusion later found to have Thyrotoxicosis (Graves' disease). MRI scans of the brain had no abnormal finding while thyroid scintigraphy showed diffuse toxic goiter. Clinical discussion: Graves' disease shares a majority of TPP while, other causes like toxic adenoma, thyroiditis, toxic multinodular goiter, amiodarone induced thyrotoxicosis, levothyroxine intoxication and thyrotropin (TSH) producing pituitary adenoma are also associated with TPP. The management of thyrotoxicosis by medical therapy, surgery or radioactive iodine therapy is the mainstay of treatment of TPP patients. For the treatment of acute attacks, potassium administration is necessary keeping in mind the problem of hyperkalemia because of excess doses of potassium as it shifts to extracellular space. Conclusion: TPP should be considered as a differential in the cases of limb weakness and the secondary causes especially Thyrotoxicosis and precipitating factors should be identified.
