Comparative analysis of related indexes of CT-guided puncture positioning between two groups of patients
| Intracavity group(n = 78) | Extracavity group(n = 69) | Statistic | p value | ||
|---|---|---|---|---|---|
| Puncture position | Supine position | 40 | 24 | χ2 = 8.481 | 0.037* |
| Prone position | 24 | 18 | |||
| Left lateral position | 9 | 18 | |||
| Right lateral position | 5 | 9 | |||
| Puncture times | 1 | 55 | 50 | χ2 = 0.132 | 0.936 |
| 2 | 20 | 16 | |||
| 3 | 3 | 3 | |||
| Positioning time (min) | 19.56 ± 3.94 | 18.75 ± 3.35 | t = 1.335 | 0.184 | |
| Distance between head of coil and nodule (mm) | 1.72 ± 0.45 | 1.76 ± 0.44 | t = 0.566 | 0.572 | |
| Position success rate (%) | 100 | 100 | – | – | |
*P value is less than 0.05, showing statistical difference.
