Aspiration Pneumonia at Recovery Room in the Patient Emergency Pelviscopic Salpingectomy, without the Perceptive Sign of Gastric Regurgitation during Perioperative Periods: A case report / 대한마취과학회지

Aspiration pneumonia is considered to be a morbid complication of anesthesia, It was reported that several conditions are associated with an increased frequency of aspiration pneumonia, such as gastroenterological, neurological and, pulmonary diseases. The incidence is also higher in emergency situations than during elective surgery. We encountered aspiration pneumonia after emergency laparoscopic salpingectomy. The patient was 25 years old woman with no prior medical history but had fasted for only 5 h in the preoperative period. During the perioperative period, there were no signs of regurgitation of the gastric contents into the oral cavity. After surgery, the patient was transported to the recovery room in a fully awakened state. However, the patient became cyanotic without vomiting. After physiotherapy, a chest CT scan was performed, and she was diagnosed with aspiration pneumonia. She was admitted to intensive care. Ten days later, she was discharged in a healthy state.

The Effect of Compressed Air Jet Cleaning on the Elimination of Postoperative Residual Protein from a ProSeal(TM) Laryngeal Mask Airway / 대한마취과학회지

BACKGROUND: The reusable ProSeal(TM) laryngeal mask airways (PLMA's) have the potential to act as a vector for the transmission of prion diseases such as variant Creutzveldt-Jacob disease. This study tested the hypothesis that supplementary compressed air jet cleaning facilitates the removal of protein deposits on PLMA's after surgery. METHODS: After clinical use, thirty PLMA's were randomly allocated to be washed by hand and with an autoclave (134 degrees C for 40 min) (group 1, n = 15), or by hand, autoclave and compressed air jet cleaning (1 min) (group 2, n = 15). In both groups, protein deposits were detected on PLMA's by erythrosine staining. A staining score designated as nil, mild, moderate, and severe was given to each site (outer, inner surface and edges of the cuff, airway and drain tube, finger strap) according to the percentage of stained surface area. The severity of staining was compared for masks prior to use and after cleaning the mask. RESULTS: Despite the cleaning of masks, the staining score worsened on the outer, inner surface and edge of PLMA's in both groups (P < 0.05); however, a similar pattern was observed on each part of a cleaned PLMA for both groups. CONCLUSIONS: We conclude that compressed air jet cleaning for 1 min did not improve the removal of protein deposits on PLMA's after surgery.
