Abstract

Osteosarcoma is a rare, malignant bone tumor commonly found in adolescents, affecting the long bones. Maxillary involvement, though less frequent, can present significant challenges in surgical resection and anesthetic management. This case describes a 16-year-old male with a maxillary osteosarcoma sinistra undergoing excision under general anesthesia, performed with difficult airway intubation devices. Endotracheal tube (ETT) insertion via nasal intubation is performed with awake intubation. At the end of surgery, the patient was extubated uneventfully and referred to ICU.

Abstract

The accuracy of intraoperative fluid resuscitation is one of the important factors influencing the outcome of surgery. In action conditions with the occurrence of fluid loss from massive "third space loss" in a fast period of time can affect fluid regulation causing ascites re-accumulation hyponatremia, hepato-renal function disorders, to shock. This case report evaluated the success of fluid replacement during massive paracentesis and post-procedure monitoring in the recovery unit. Case description: 5-year-old girl, with massive ascites suspicious of malignancy planned to undergo a paracentesis procedure. The patient had clinical abdominal distention, mild-moderate dehydration, vomiting, and decreased skin turgor. Another abnormality found was a hydrocephalus post-VP Shunt in 2023. The patient was assessed as ASA 3 based on his physical status. Maintenance fluids are calculated to meet basal metabolic needs during surgery based on the Holliday-Segar formula using the 4-2-1 rule. Fluid resuscitation during procedure can be performed with crystalloid, typically 40-60 mL/kg, with a bolus of 10-20 mL/kg to assess fluid responsiveness. In conclusion, fluid administration was carried out using goal-directed fluid therapy, where fluid resuscitation is adjusted based on various hemodynamic parameters.

Abstract

Background: Airway management is critical in pediatric anesthesia, as failure can lead to severe complications, including cardiac arrest. Anticipating and preparing for difficult intubation is essential, particularly in children with unique anatomical and physiological characteristics. The Colorado Pediatric Airway Score (COPUR) is a predictive tool for assessing intubation difficulty in pediatric patients.Objective: This study evaluates the validity of COPUR in predicting difficult intubation in children.Methods: A cross-sectional diagnostic study was conducted on 121 pediatric patients (aged 1–8 years) undergoing general anesthesia at Cipto Mangunkusumo Hospital. COPUR assesses jaw structure, mouth opening, prior intubation history, uvula visibility, neck movement, and additional modifying factors (macroglossia, obesity, mucopolysaccharidosis, and protruding teeth). A COPUR score >7 was used to predict difficult intubation, while intubation difficulty was defined by an Intubation Difficulty Score (IDS) >5.Results: A COPUR score ≥8 predicted difficult intubation in 15.7% of patients, whereas actual difficult intubation occurred in 9.92%. A COPUR threshold of ≥7 provided optimal sensitivity (83.3%) and specificity (61.47%), outperforming the original cutoff of 8 (50% sensitivity, 87% specificity). The score demonstrated good discriminative ability (AUC-ROC: 0.770, 95% CI: 0.685–0.842) and suitable calibration (Hosmer-Lemeshow test, p = 0.584).Conclusion: The COPUR score is a valid tool for predicting difficult intubation in pediatric patients aged 1–8 years, demonstrating fairly good discrimination and calibration values.
