Anesthetic Management for Paraesophageal Hernia Repair

Anaesthesia Management for Giant Intraabdominal Tumours: A Case Series Study

BACKGROUND

Due to a lack of randomised controlled trials and guidelines, and only case reports being available in the literature, there is no consensus on how to approach anaesthetic management in patients with giant intraabdominal tumours.

METHODS

This study aimed to evaluate the literature and explore the current status of evidence, by undertaking an observational research design with a descriptive account of characteristics observed in a case series referring to patients with giant intraabdominal tumours who underwent anaesthesia.

RESULTS

Twenty patients diagnosed with giant intraabdominal tumours were included in the study, most of them women, with the overall pathology being ovarian-related and sarcomas. Most of the patients were unable to lie supine and assumed a lateral decubitus position. Pulmonary function tests, chest X-rays, and thoracoabdominal CT were the most often performed preoperative evaluation methods, with the overall findings that there was no atelectasis or pleural effusion present, but there was bilateral diaphragm elevation. The removal of the intraabdominal tumour was performed under general anaesthesia in all cases. Awake fiberoptic intubation or awake videolaryngoscopy was performed in five cases, while the rest were performed with general anaesthesia with rapid sequence induction. Only one patient was ventilated with pressure support ventilation while maintaining spontaneous ventilation, while the rest were ventilated with controlled ventilation. Hypoxemia was the most reported respiratory complication during surgery. In more than 50% of cases, there was hypotension present during surgery, especially after the induction of anaesthesia and after tumour removal, which required vasopressor support. Most cases involved blood loss with subsequent transfusion requirements. The removal of the tumor requires prolonged surgical and anaesthesia times. Fluid drainage from cystic tumour ranged from 15.7 L to 107 L, with a fluid extraction rate of 0.5-2.5 L/min, and there was no re-expansion pulmonary oedema reported. Following surgery, all the patients required intensive care unit admission. One patient died during hospitalization.

CONCLUSIONS

This study contributes to the creation of a certain standard of care when dealing with patients presenting with giant intraabdominal tumour. More research is needed to define the proper way to administer anaesthesia and create practice guidelines.

Anesthesia management of a patient with Meigs' syndrome: A case report and literature review

INTRODUCTION

Herein, we describe a case of Meigs' syndrome, a complex condition that poses a challenge for anesthesiologists to manage. Good anesthetic management of this syndrome is necessary to preserve the prognosis.

PRESENTATION OF CASE

An 80-year-old woman was admitted to the emergency department with complaints of abdominal pain, particularly in the left lower abdomen, with aggravation after activity. The patient was unable to sleep in a supine position. Her serum carbohydrate antigen 125 level was 253.15 U/mL-1, and laboratory examinations were nonspecific. On auscultation, breath sounds were absent from the base of the right lung. Abdominal computed tomography (CT) was performed to screen for a possible tumor consisting of both solid and cystic components, but the findings were inconclusive. Chest CT showed large right pleural effusions and hiatal hernia.

DISCUSSION

A multidisciplinary team conducted careful preoperative preparation, while the anesthesiology team prepared detailed peri-anesthesia management strategies to regulate acid-base and electrolyte balance and maintain respiratory and hemodynamic stability. The surgeon resected the tumor successfully. The patient was discharged after 1 week. A postoperative pathology test confirmed fibrothecomas.

CONCLUSION

We provided an effective strategy for the anesthetic management of Meigs' syndrome, which remains a complex challenge for anesthesiologists. It is important that anesthesiologists perform adequate preoperative evaluation and prudent peri-anesthesia management to ensure that patients have a good prognosis and discharge healthily. A multidisciplinary team is essential when caring for patients with Meigs' syndrome.

Anesthesia management of an aged patient with giant abdominal tumor and large hiatal hernia: A case report and literature review

INTRODUCTION

A giant abdominal tumor with a large hiatal hernia remains a rare disease with few studies regarding its implications in anesthesia. A large hiatal hernia may compress the heart and cause arrhythmia and even cardiac arrest, which greatly increases the risks and challenges of anesthesia management.

CASE DESCRIPTION

We present a case in which a patient with a giant abdominal desmoid tumor and large hiatal hernia experienced a critical situation during anesthesia and surgery.

CONCLUSIONS

It is a great challenge for anesthesiologists to manage a patient's respiratory system and circulation. Careful perioperative management and optimized multidisciplinary teams are the key factors in the successful management of this rare condition. In addition, awake endotracheal intubation, ventilation preserving spontaneous breathing and target-directed fluid therapy play an essential role in anesthesia management.

Analysis of the Risk Factors for Hypotension in Laparoscopic Hiatal Hernia Repair

Objective

This study aimed to investigate the risk factors for hypotension in patients undergoing laparoscopic hiatal hernia repair.

Methods

The clinical data of patients who underwent laparoscopic repair of a hiatal hernia in the Beijing Chao-Yang Hospital of Capital Medical University between February 2018 and January 2021 were retrospectively collected, and their perioperative data were obtained by querying the electronic medical record system. The patients were divided into two groups—a hypotension group and a normal group—based on the occurrence of intraoperative hypotension, which was defined as a mean arterial pressure <65 mmHg and lasting ≥1 minute during the operation. The variables with a P value ≤0.1 in univariate regression analysis and clinically considered relevant variables were included in multivariate regression analysis in order to screen the risk factors for hypotension in these patients.

Results

A total of 114 patients were included in the analysis. The incidence of hypotension was 54.4%. Old age was identified as the only risk factor for hypotension during hiatal hernia surgery.

Conclusion

Old age is the only risk factor for intraoperative hypotension in patients undergoing laparoscopic hiatal hernia repair.
