i this what I think it is?

18 We have been with child, we have been in pain, we have as it were brought forth wind; we have not wrought any deliverance in the earth; neither have the inhabitants of the world fallen.

Please enlighten my carnal mind...what does it mean when it says they have "brought forth wind?"

Graphic sounding text... but to me it describes our (professing Christians)helplessness in attaining to a righteous state (we have not wrought any deliverance), neither have the inhabitants of the world fallen (fallen world? - worldlings). But the next verse shows Isaiah's faith, that the Lord will deliver those who are His.

Haha thanks. I thought it was flatulence but now i see it was the pain of child birth that brought forth nothing

We have been … - This refers to sorrows and calamities which they had experienced in former times, when they had made great efforts for deliverance, and when those efforts had proved abortive. Perhaps it refers to the efforts of this kind which they had made during their painful captivity of seventy years. There is no direct proof indeed, that during that time they attempted to revolt, or that they organized themselves for resistance to the Babylonian power; but there can be no doubt that they earnestly desired deliverance, and that their condition was one of extreme pain and anguish - a condition that is strikingly represented here by the pains of childbirth. Nay, it is not improbable that during that long period there may have been abortive efforts made at deliverance, and that here they refer to those efforts as having accomplished nothing.

We have as it were brought forth wind - Our efforts have availed nothing.

Neither have the inhabitants of the world fallen - We had no power to subdue them; and notwithstanding all our exertions their dominion was unbroken. This refers to the Babylonians who had dominion over the captive Jews.
