“…PVI was shown to predict fluid responsiveness in mechanically ventilated neonates and infants during surgery 16,17 . PVI was significantly increased at the onset of shock in neonates 18 . Our study showed no significant difference in PVI values between neonates with proven/probable sepsis and no‐sepsis and between non‐survivors versus survivors.…”

“…16,17 PVI was significantly increased at the onset of shock neonates. 18 Our showed no significant difference in PVI values between neonates with proven/probable sepsis and no-sepsis and between non-survivors versus survivors. Thus, PVI may not assist in identifying potential non-survivors in the early stages of neonatal sepsis.…”

“…PI and PVI were recorded by RAD‐7 or RAD‐97 monitors every hour till 120 h after enrolment. The monitors calculated PI as a ratio of pulsatile blood flow (AC) and the non‐pulsatile blood flow (DC), that is, PI = AC/DC × 100, and PVI as a ratio of difference in maximum and minimum PI and maximum PI as (PI max − PI min )/PI max × 100% 11,18 . We performed blood‐gas analysis in the Radiometer ABL‐800 machine using arterial or arterialised capillary samples.…”

“…The enrolled neonates were attached to the multichannel monitor that is, PI = AC/DC × 100, and PVI as a ratio of difference in maximum and minimum PI and maximum PI as (PI max − PI min )/PI max × 100%. 11,18 We performed blood-gas analysis in the Radiometer ABL-800 machine using arterial or arterialised capillary samples. The data entered was crosschecked at the end of every shift by a study investigator (AS).…”

Aim(i) To compare perfusion index (PI) and plethysmography variability index (PVI) between neonates with proven or probable sepsis versus no‐sepsis, (ii) to examine an association of PI and PVI with in‐hospital mortality.MethodsWe enrolled neonates with clinically presumed sepsis. Culture‐proven or probable sepsis were categorised as ‘cases’ and no‐sepsis as ‘controls’. PI and PVI were recorded hourly for 120 h and averaged in 20‐time epochs (0–6 h to 115–120 h).ResultsWe analysed 148 neonates with sepsis (proven sepsis = 77, probable sepsis = 71) and 126 with no‐sepsis. Neonates with proven/probable sepsis and no‐sepsis had comparable PI and PVI values. Among 148 neonates with sepsis, 43 (29%) died. Non‐survivors had significantly lower PI values than survivors (mean difference 0.21 [95% CI 0.14–0.29], p‐value <0.001). PI had a significant but modest discriminative ability to identify non‐survivors. However, PI did not independently predict mortality.ConclusionNeonates with proven/probable sepsis and no‐sepsis had comparable PI and PVI values in the first 120 h of sepsis. PI but not PVI values were significantly lower in non‐survivors than survivors. PI did not independently predict in‐hospital mortality. Due to modest discriminative ability, PI should be interpreted along with other vital signs to take clinical decisions.

With the development of neonatal medicine, more and more extremely preterm infants have been treated. How to deal with hypotension is a big challenge for neonatologist in the process of diagnosis and treatment. The lack of uniformity in the definition of hypotension, challenges in measuring blood pressure accurately, and insufficient consistency between digital hypotension and hypoperfusion are the primary causes. How to check for hypotension and monitor blood pressure is thoroughly explained in the article. To give neonatologists a resource for the clinical management of hypotension in extremely preterm.
