Description

TECHNICAL FIELD The present disclosure relates to the field of surgical drapes and in particular to caesarean section (C-section) surgical drapes. BACKGROUND In traditional caesarean section procedures, commonly known to as "C-sections," the patient is typically covered with a solid surgical drape. This drape is typically made of a multi-layered combination of spunbond and meltblown nonwoven materials, along with a liquid-impervious plastic film functioning as a barrier layer. The spunbond and meltblown nonwoven materials are absorbent materials which are also conventionally coloured materials. During the procedure the mother is typically awake. Many conventional drapes are designed in a "T" shape, with the top portion of the "T" functioning as an anesthesia screen to provide a barrier or screen to create a sterile field around the abdomen. The anesthesia screen is held up on vertical supports at each side of the operating table near the patient's head or on a crossbar positioned close to the head. In this setup, the mother may lack the opportunity to see her newborn immediately after delivery. However, establishing an immediate connection between mother and child in the first moments after birth is highly beneficial, particularly through skin-to-skin contact. Such contact is believed to offer numerous advantages for both mother and infant. Traditional surgical drapes, however, block the mother's view of her newborn in those initial moments, preventing this immediate physical connection. To address this limitation, some surgical drapes have been developed with a window and a coverable layer that may obscure or expose the window. SUMMARY One objective of the present disclosure is to make available a surgical drape which enables the mother, during a C-section, to see and hold her newborn baby immediately after delivery, which surgical drape is also easy and convenient to use, both before and throughout the procedure, facilitating an enhanced bonding experience without compromising the sterile environment. According to a first aspect, the present disclosure makes available a surgical drape having a lateral extension and a longitudinal extension, the surgical drape being divided in an upper region for arrangement proximal a head of a patient during surgical procedure and a lower region arranged proximal a surgical site of the patient, the upper region being divided in a first lateral section, a central section and a second lateral section, the surgical drape further comprising: a surgeon facing barrier sheet being essentially liquid impermeable and transparent, the surgeon facing barrier sheet extending over the first lateral section, the central section and the second lateral section of the upper region,a patient facing sheet being essentially opaque, the patent facing sheet extending over the central section of the upper region,a fenestration arranged in the lower region, the fenestration permitting access to the surgical site when the surgical drape covers a patient during surgical procedures,a first and a second limb portion arranged in the surgeon facing barrier sheet in the upper region of the surgical drape, the first and second limb portions each comprising a base portion attached to the surgical drape, a closed end portion and a sleeve portion extending between the base portion and the end portion, wherein the surgeon facing barrier sheet extends beyond the patient facing sheet along a respective first and second longitudinal edge of the patient facing sheet in the upper region. The term "essentially opaque" is used to describe the property where very little or no light passes through the material making object behind the material difficult or impossible to discern. Examples of such materials are nonwoven materials, such as multi-layer nonwovens, for examples combination of spunbond and meltblown nonwoven layer. The nonwoven material, or multilayer nonwoven may have a basis weight over 30 gsm, or over 40 gsm. A further example is a coloured nonwoven material. A further example is an opaque plastic film, such as a polyethylene film. The patient facing sheet may have an opacity of at least 60%, or at least 70%, or at least 75%, or at least 80%, as measured according to the method ASTM D 2244-22. The surgeon facing barrier sheet is a transparent, essentially liquid impermeable, sheet, such as a clear plastic film. The transparent barrier sheet may have a Haze level from 30% or lower, as measured according to ASTM D 1003. Optionally, the transparent barrier sheet has Haze level from 25% or lower, or 20% or lower, or 10% or lower, or 5% or lower, as measured according to ASTM D 1003. Optionally, the surgeon facing barrier sheet has a liquid penetration of ≥ 100 cm H2O, as measured according to ISO 811. The surgeon facing barrier sheet serves both as a protective barrier and a viewing window, allowing the mother to see her newborn baby immediately after delivery during a C-section. However, there may be inst
