Efficacy and safety of intraoperative partial spray of 50% glucose for patients with spontaneous pneumothorax.

The management for pneumothorax patients involves surgical intervention, nevertheless postoperative recurrences are often encountered. To reduce the rates of recurrence, thoracic surgeons have experimented with various novel techniques, such as pleural abrasion, chemical pleurodesis, and staple line coverage with absorbable sheets, in addition to bullectomy. And in recent years, there have been reports of the effectiveness of the use of intraoperative glucose intrapleural spray (GIS) containing 50 ml of 50% glucose solution in addition to bullectomy. However, information on the effects and adverse events of GIS is limited. Current study was aimed to assess the efficacy and safety of GIS in preventing recurrence of pneumothorax. We conducted a retrospective study with 74 cases of bullectomy with or without GIS between 2018 and 2021 at Okazaki City Hospital. Of these cases, 50 received GIS (GIS group) while 24 were treated conservatively (C group). The GIS group consisted of 46 males and 4 females, whereas the C group consisted of 23 males and 1 female, with mean ages of 38.5 ± 5.7 years and 30.5 ± 6.7 years, respectively. The GIS group exhibited a mean increase in blood glucose of 23.8 mg/dL postoperatively, and postoperative infections were observed in 2 cases in the GIS group (4.0%) and 2 cases in the C group (8.3%). The NRS scores of the patients in the GIS group and the C group three hours postoperatively were 4.0 and 3.1, respectively (p = 0.28). No prolongation of postoperative drainage period by GIS was observed (1.2 days and 1.4 days in the GIS and C groups, respectively). Postoperative recurrence occurred in two patients from the C group. The postoperative total drainage volumes were 341.8 ± 25.2 ml and 74.2 ± 25.5 ml in the GIS and C groups, respectively, showing a significant increase in drainage volume (p < 0.01). None of them presented dehydration-related symptoms. The use of intraoperative glucose intrapleural spray is effective and safe in terms of preventing recurrences and postoperative complications. © 2024. The Author(s).
