is a painful event and its pain is one of the most severe one. Reducing this
pain, for lowering the negative effects on pregnant women and also labor
progress, has always been under serious concern. The purpose of the present
study was to compare the effect of entonox and oxygen for lowering labor pain
and also its effect on the progress of labor.&lt;/span&gt;&lt;span style=&quot;font-size: 13pt mso-bidi-font-family: &quot;B Mitra&quot;&quot;&gt;&lt;o:p /&gt;&lt;/span&gt;&lt;/p&gt;&lt;font face=&quot;Times New Roman&quot; size=&quot;3&quot;&gt; &lt;/font&gt;&lt;p class=&quot;MsoNormal&quot; style=&quot;margin: 0in 0in 0pt -0.05pt text-align: justify line-height: normal text-justify: kashida text-kashida: 0%&quot;&gt;&lt;b&gt;&lt;span style=&quot;font-family: &quot;Times New Roman&quot;,&quot;serif&quot; font-size: 12pt&quot;&gt;Methods&lt;/span&gt;&lt;/b&gt;&lt;span style=&quot;font-family: &quot;Times New Roman&quot;,&quot;serif&quot; font-size: 12pt&quot;&gt;: A randomized
clinical trial was performed on 120 nulliparas pregnant women who had been
admitted in the labor ward of Akbarabadi Teaching Hospital for termination of pregnancy,
They had labor pain and were in the active phase of labor, thus enterd the study
and randomly were assigned into the two groups of entonox (case group) and
oxygen group (control group) (each group with 60 women). Pain was evaluated
using Visual Analogue Scale (VAS). Duratin of the active phase and second stage
of labor and also the total duration of labor and pain and adverse effects were
compared between the two groups.&lt;o:p /&gt;&lt;/span&gt;&lt;/p&gt;&lt;font face=&quot;Times New Roman&quot; size=&quot;3&quot;&gt; &lt;/font&gt;&lt;p class=&quot;MsoNormal&quot; style=&quot;margin: 0in 0in 0pt text-align: justify line-height: normal text-justify: kashida text-kashida: 0% tab-stops: right 7.3pt center 265.9pt&quot;&gt;&lt;b&gt;&lt;span style=&quot;font-family: &quot;Times New Roman&quot;,&quot;serif&quot; font-size: 12pt&quot;&gt;Results:&lt;/span&gt;&lt;/b&gt;&lt;span style=&quot;font-family: &quot;Times New Roman&quot;,&quot;serif&quot; font-size: 12pt&quot;&gt; The women of
the two groups did not have significant differences according to age (p= 0.6),
gestational age (p= 0.4), BMI (p= 0.9), neonatal weight (p- 0.6), Apgar score
of 1 and 5 minutes and cesarean deliveries (p= 0.2). Mean pain score at
different times (hours 1, 2, and 3) (p&lt; 0.05) was lower in entonox group. Mean
duration of labor (p= 0.003), active phase of labor (p= 0.02), and second stage
of labor (p=0.02) were lower in entonox group. Side effects were more in the
entonox group (p= 0.001). &lt;o:p /&gt;&lt;/span&gt;&lt;/p&gt;&lt;font face=&quot;Times New Roman&quot; size=&quot;3&quot;&gt; &lt;/font&gt;&lt;p class=&quot;MsoNormal&quot; style=&quot;margin: 0in 0in 0pt -0.05pt text-align: justify line-height: normal text-justify: kashida text-kashida: 0%&quot;&gt;&lt;b&gt;&lt;span style=&quot;font-family: &quot;Times New Roman&quot;,&quot;serif&quot; font-size: 12pt&quot;&gt;Conclusions: &lt;/span&gt;&lt;/b&gt;&lt;span style=&quot;font-family: &quot;Times New Roman&quot;,&quot;serif&quot; font-size: 12pt&quot;&gt;Entonox is
effective for pain relief. It also reduces the duration of labor, however, its
side effects are more than oxygen.&lt;/span&gt;&lt;span style=&quot;color: black font-family: &quot;Times New Roman&quot;,&quot;serif&quot; font-size: 14pt mso-bidi-language: FA mso-bidi-font-family: &quot;B Lotus&quot;&quot;&gt;&lt;o:p /&gt;&lt;/span&gt;&lt;/p&gt;&lt;font face=&quot;Times New Roman&quot; size=&quot;3&quot;&gt; &lt;/font&gt;</abstract>
