The purpose of this study was to compare the therapeutic effects of a pigtail catheter with a chest tube in the management of patients with spontaneous pneumothorax (SP).
A randomized controlled trial study was performed on patients with SP from August 2016 to December 2017 at Imam Reza Hospital, Tabriz, Iran. Forty-four patients were randomly assigned into 2 groups: group A with a 14-Fr pigtail catheter and group B using a 28-Fr chest tube. Two patients were excluded from the study.
Forty-two patients participated in the study with 21 patients in each group. There were no significant differences between the groups in the patients' baseline data. The success rate was higher in patients with pigtail catheters (85.7%) than in patients with chest tubes (76.2%). However, the difference was not significant (P = .43). The procedure time was significantly shorter in the pigtail group compared to the chest tube group (P < .01). According to the visual analog scale (VAS), patients with pigtail catheters experienced milder pain during tube insertion than patients with chest tubes (P = .02). However, the pain score at the insertion site was not significantly different between the 2 groups for the first 2 days after the procedure. Patients with pigtail catheters experienced significantly less pain than patients with chest tubes during removal of the tube (P < .01). Also, there was no significant difference between the pain experienced by the 2 groups at the time of hospital discharge (P = .19). Analgesic drug usage was lower in patients with pigtail catheters compared to patients with chest tubes (P < .01). There was a trend toward lower median hospital stays demonstrated by patients with pigtail catheters compared to patients with chest tubes (P = .2).
Pigtail catheters might be as effective as chest tubes for treating patients with SP in terms of lung re-expansion.
本研究旨在比较猪尾导管与胸管在自发性气胸（SP）患者治疗中的效果。
2016年8月至2017年12月在伊朗大不里士伊玛目礼萨医院对SP患者进行了一项随机对照试验研究。44例患者被随机分为2组：A组使用14F猪尾导管，B组使用28F胸管。2例患者被排除在研究之外。
42例患者参与研究，每组21例。两组患者的基线数据无显著差异。猪尾导管组患者的成功率（85.7%）高于胸管组患者（76.2%）。然而，差异不显著（P = 0.43）。与胸管组相比，猪尾导管组的操作时间显著更短（P < 0.01）。根据视觉模拟量表（VAS），猪尾导管组患者在置管期间的疼痛比胸管组患者更轻（P = 0.02）。然而，术后前两天两组在置管部位的疼痛评分无显著差异。猪尾导管组患者在拔管时的疼痛明显低于胸管组患者（P < 0.01）。此外，两组患者出院时的疼痛无显著差异（P = 0.19）。与胸管组患者相比，猪尾导管组患者的镇痛药使用量更低（P < 0.01）。与胸管组患者相比，猪尾导管组患者的中位住院时间有缩短趋势（P = 0.2）。
在肺复张方面，猪尾导管治疗SP患者可能与胸管一样有效。
