(1) Background: SCUBA diving can influence changes of several hematological parameters (HP) but the changes of HP in the decompression phases are still unclear. The aim of this study was to investigate any possible relationship between HP and predisposition to inert gas bubble formation after a single recreational dive. (2) Methods: Blood, obtained from 32 expert SCUBA divers, was tested for differences in white blood cells (WBC), granulocytes (GRAN), lymphocytes (LYM), and monocytes (MONO), red blood cells (RBC), and platelets (PLT) between bubblers (B) and non-bubblers (NB). (3) Results: We found inter-subject differences in bubble formation (considering the same diving profile performed by the divers) and a statistically significant higher number of total WBC, GRAN and LYM in NB as compared to the B divers in the pre and in the post diving sample, while no statistical differences were found for MONO and PLT. In addition, we did not find any statistically significant difference between NB and B in RBC. (4) Conclusions: Our results, even if in absence of investigated anti-inflammatory markers, could indicate a relationship between low WBC numbers and bubble formation. This aspect may explain a possible cause of inter-subject differences in bubble formation in divers performing the same dive profile.
(1) 背景：水肺潜水会影响多个血液学参数（HP）的变化，但减压阶段HP的变化仍不清楚。本研究的目的是调查单次休闲潜水后HP与惰性气体气泡形成易感性之间的任何可能关系。(2) 方法：从32名专业水肺潜水员采集血液，检测气泡形成者（B）和无气泡形成者（NB）之间白细胞（WBC）、粒细胞（GRAN）、淋巴细胞（LYM）、单核细胞（MONO）、红细胞（RBC）和血小板（PLT）的差异。(3) 结果：我们发现潜水员进行相同潜水剖面时，个体间气泡形成存在差异，并且在潜水前和潜水后的样本中，与B组潜水员相比，NB组潜水员的白细胞、粒细胞和淋巴细胞总数在统计学上显著更高，而单核细胞和血小板未发现统计学差异。此外，我们未发现NB组和B组在红细胞方面存在任何统计学显著差异。(4) 结论：我们的结果，即使在未研究抗炎标志物的情况下，也可能表明白细胞数量低与气泡形成之间存在关系。这一方面可能解释了进行相同潜水剖面的潜水员中个体间气泡形成差异的一个可能原因。
