Fetal instability occurred in 51 of 245 cases (20.8%), with rates varying significantly by procedure type (30\/35 FASI, 85.7% vs. 21\/210 fMMC, 10.0%,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.01). The causes of fetal instability requiring resuscitation differed by procedure. In FASI, all instability was procedure\u2010related, whereas instability during fMMC repairs was most often related to the uterine environment. Invasive resuscitative interventions (e.g.,\u00a0pericardiocentesis) were used exclusively in FASI. In fMMC repair, less invasive interventions (e.g.,\u00a0repositioning) were more commonly employed.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Fetal instability is common during fetal interventions, with higher rates and more invasive resuscitation during FASIs compared with fMMC repairs.
