Diabetes insipidus associated with propofol anesthesia

Analysis of factors associated with polyuria in spinal surgery: a retrospective study

BACKGROUND

Intraoperative urine output monitoring is an important indicator to judge patient volume, and perioperative polyuria can lead to a variety of complications, which seriously affect the quality of prognosis of patients. Previous studies have found that intraoperative polyuria in some patients may be associated with the use of anesthetic drugs, especially in spinal surgery patients, where cases of polyuria have been reported more commonly. Therefore, this retrospective study focused on the factors influencing polyuria during spinal surgery.

METHODS

Data from spine surgery patients in the Madison system of Tongji Hospital from September 2018 to December 2021 were collected. The age, sex, BMI, surgical information, preoperative and postoperative test results, LOS, and postoperative adverse reactions were extracted. The relevant data during the operation were recorded through the Madison system at the same time, including the time statistics of various types of surgery, the amount of liquid in and out of the operation, the use of anesthetic drugs, the use of vasoactive medications, and the results of blood gas analysis. The primary outcome was to analyze the factors influencing intraoperative polyuria. Secondary outcomes were analyzed, among adverse effects of intraoperative polyuria, etc. RESULTS: Among the 903 included patient data, we concluded that the factors influencing intraoperative polyuria were female (OR, 1.933, 95% CI, 1.457-2.565), dexmedetomidine (OR, 1.876, 95% CI, 1.338-2.631), dopamine (OR, 1.413, 95% CI, 1.406-1.910). At the same time, different surgical sites also affected the symptoms of polyuria (p < 0.001). Intraoperative polyuria symptoms led to an increase in the incidence of infection (p < 0.05) and secondary surgery (p < 0.05). The length of hospital stay was also increased (p < 0.05) compared with the normal urine output group. There was no significant difference in the time of operation and preoperative and postoperative examination information(p > 0.05).

CONCLUSIONS

Females, dexmedetomidine, dopamine may be risk factors for intraoperative polyuria. Intraoperative polyuria will lead to various postoperative adverse reactions, increasing the proportion of postoperative infection and secondary surgery.

Establishment and validation of a predictive nomogram for polyuria during general anesthesia in thoracic surgery

BACKGROUND

To develop and evaluate a predictive nomogram for polyuria during general anesthesia in thoracic surgery.

METHODS

A retrospective study was designed and performed. The whole dataset was used to develop the predictive nomogram and used a stepwise algorithm to screen variables. The stepwise algorithm was based on Akaike's information criterion (AIC). Multivariable logistic regression analysis was used to develop the nomogram. The receiver operating characteristic (ROC) curve was used to evaluate the model's discrimination ability. The Hosmer-Lemeshow (HL) test was performed to check if the model was well calibrated. Decision curve analysis (DCA) was performed to measure the nomogram's clinical usefulness and net benefits. P < 0.05 was considered to indicate statistical significance.

RESULTS

The sample included 529 subjects who had undergone thoracic surgery. Fentanyl use, gender, the difference between mean arterial pressure at admission and before the operation, operation type, total amount of fluids and blood products transfused, blood loss, vasopressor, and cisatracurium use were identified as predictors and incorporated into the nomogram. The nomogram showed good discrimination ability on the receiver operating characteristic curve (0.6937) and is well calibrated using the Hosmer-Lemeshow test. Decision curve analysis demonstrated that the nomogram was clinically useful.

CONCLUSIONS

Individualized and precise prediction of intraoperative polyuria allows for better anesthesia management and early prevention optimization.

Dexmedetomidine-associated diabetes insipidus during skull base surgery in a pediatric patient

Diabetes insipidus is characterized by polyuria due to an inability to auto-regulate water balance resulting in dangerous metabolic derangements. Intraoperative anesthetics have been increasingly identified as a cause of diabetes insipidus in adult patients; however, it is rare in pediatrics. We present a case of a 16-year-old male undergoing resection of a recurrent left juvenile nasopharyngeal angiofibroma who experienced intraoperative polyuria concerning diabetes insipidus. Urine output drastically decreased following discontinuation of dexmedetomidine with complete resolution within 24 h. We conclude that this case of transient diabetes insipidus was associated with dexmedetomidine administration.

Perioperative Diabetes Insipidus Caused by Anesthetic Medications: A Review of the Literature

Diabetes insipidus (DI) is an uncommon perioperative complication that can occur secondary to medications or surgical manipulation and can cause significant hypovolemia and electrolyte abnormalities. We reviewed and evaluated the current literature and identified 24 cases of DI related to medications commonly used in anesthesia such as propofol, dexmedetomidine, sevoflurane, ketamine, and opioids. This review summarizes the case reports and frequency of DI with each medication and presents possible pathophysiology. Medication-induced DI should be included in the differential diagnosis when intraoperative polyuria is identified. Early identification, removal of the agent, and treatment of intraoperative DI are critical to minimize complications.

Effects of anesthetics on post-operative 3-month neuroendocrine function after endoscopic transsphenoidal non-functional pituitary adenoma surgery

BACKGROUND

Anesthetic techniques can affect perioperative neuroendocrine function. The objective of this study was to compare 3-month post-operative neuroendocrine functional outcomes between sevoflurane and propofol anesthesia in patients undergoing endoscopic transsphenoidal surgery (ETS) for removal of non-functional pituitary adenomas (NFPAs) retrospectively.

METHODS

Among 356 patients who underwent ETS for removal of NFPAs under sevoflurane-remifentanil anesthesia (sevoflurane group, n = 103) or propofol-remifentanil anesthesia (propofol group, n = 253), 92 patients in each group were selected and their 3-month post-operative neuroendocrine functional outcomes (primary outcome measure) were compared after propensity score matching.

RESULTS

Overall changes in post-operative 3-month neuroendocrine function compared to pre-operative baseline did not differ between the sevoflurane and propofol groups (worsened: 32.6% vs 29.3%, persistently decreased: 9.8% vs 12.0%, improved: 12.0% vs 20.7%, normalized: 9.8% vs 12.0%, persistently normal: 18.5% vs 19.6%; P = .400). The incidence of pituitary hormone deficiency at 3 months post-operatively did not differ between the sevoflurane and propofol groups (adrenocorticotropic hormone deficiency: 18.5% vs 17.4%, P = 1.000; thyroid-stimulating hormone deficiency: 10.9% vs 3.3%, P = .081; gonadotropin deficiency: 54.3% vs 48.9%, P = .555; growth hormone deficiency: 45.7% vs 48.9%, P = .768; panhypopituitarism: 1.1% vs 1.1%, P = 1.000).

CONCLUSION

In patients undergoing ETS for removal of NFPAs, the effects of both sevoflurane-remifentanil and propofol-remifentanil anesthetic techniques on post-operative 3-month neuroendocrine functional outcomes were similar, suggesting that propofol and sevoflurane can be freely used in such patients in terms of post-operative intermediate-term neuroendocrine functional outcome.

Acute onset of central diabetes insipidus during adolescent idiopathic scoliosis surgery

This is a case report of a 12-year-old female with idiopathic scoliosis undergoing posterior scoliosis reconstruction that developed an acute onset of central diabetes insipidus (CDI) during surgery. The diagnosis was made as a result of an intraoperative increase in urine output to 6.82 ml/kg/hour (550 ml), a serum sodium increase from 139 to 147 mmol/L, a serum osmolality of 299 mOsmol/kg, a rapid response to vasopressin administration and a low vasopressin level of < 0.5 picograms/ml (normal, 1-5 picograms/ml). This is the first reported case of CDI with a documented low vasopressin level that has occurred in a pediatric scoliosis surgical patient.

Severe Disruption of Water and Electrolyte Balance After Appendectomy: A Case Report

Perioperative derangements of fluid and electrolyte homeostasis are rare complications in healthy children. Nonetheless, early diagnosis and treatment are mandatory to avoid a potentially life-threatening situation. However, the variety of underlying pathologies may prove to make accurate diagnosis challenging. This case report presents the management of an unexpected occurrence of a perioperative partial diabetes insipidus with massive fluid loss. Diagnostic and therapeutic procedures are discussed in the context of laboratory findings, and an overview of the existing literature is given. Finally, we emphasize that a multidisciplinary approach is most appropriate for diagnosis, accurate treatment, and follow-up of the patient.

Transient Intraoperative Central Diabetes Insipidus in Moyamoya Patients Undergoing Revascularization Surgery: A Mere Coincidence?

We present 2 patients with Moyamoya disease undergoing revascularization surgery who developed transient intraoperative central diabetes insipidus with spontaneous resolution in the immediate postoperative period. We speculate that patients with Moyamoya disease may be predisposed to a transient acute-on-chronic insult to the arginine vasopressin-producing portion of their hypothalamus mediated by anesthetic agents. We describe our management, discuss pertinent literature, and offer possible mechanisms of this transient insult. We hope to improve patient safety by raising awareness of this potentially catastrophic complication.
